SIP10 Package

The new 2S10B1_7UP series is a 2 Watt isolated, unregulated DC/DC converter housed in a compact SIP10 package, engineered for applications with stringent requirements on patient safety, isolation strength, and long-term reliability. With a fixed 12 VDC input and output voltages of 5 V or 12 V, the series reliably serves typical supply tasks on 12 V industrial and medical buses.

The standout feature of the series is its reinforced isolation of 7,000 VDC between input and output, together with a full-load impulse withstand voltage of 8 kV — characteristics that securely protect patient-side supplies and industrial high-voltage isolation tasks. Despite these high isolation figures, the series achieves an exceptionally low isolation capacitance of just 7 pF, significantly reducing common-mode noise in the system.

Designed for outstanding reliability, the 2S10B1_7UP series achieves an impressive MTBF of 3,500,000 hours (MIL-HDBK-217F @ 25 °C). It operates stably across an extended temperature range from -40 °C to +105 °C (with derating from 71 °C) and is equipped with continuous, self-recovering short-circuit protection. Efficiency reaches up to 84 % at full load, with typical ripple & noise of 50 mVp-p.

Operating at a switching frequency of 260 kHz, with EMC compliance per CISPR32/EN 55032 Class B and high ESD immunity (air ±8 kV, contact ±6 kV), the series provides a stable, clean supply for sensitive downstream electronics. The flame-retardant black plastic case is certified to UL94 V-0.

In medical equipment, the 2S10B1_7UP series is particularly well suited for patient-side signal supplies in ECG, EEG, and EMG devices, for the front-end electronics of SpO₂ and non-invasive blood-pressure measurement, and for portable point-of-care diagnostic devices. Beyond medical, it reliably serves isolated signal supplies in industrial bus and sensor interfaces as well as in measurement and test equipment — wherever high isolation, low coupling capacitance, and a compact form factor are required simultaneously.

SIP12 Package

The new 2S12B_10RP series is a 2 Watt isolated, regulated DC-DC converter developed specifically for applications with the highest isolation requirements. Housed in a SIP12 package measuring 33.0 x 10.5 x 15.5 mm, the series provides an outstanding isolation voltage of 10,000 VDC between input and output — a value far beyond typical standard requirements that opens up new design freedom for safety-critical and high-voltage-adjacent circuits.

With an efficiency of up to 90 % at full load and a low ripple & noise of typically 50 mVp-p (20 MHz bandwidth), the 2S12B_10RP delivers a stable and clean supply for sensitive downstream assemblies. The series is available across a broad range of voltage variants: 5 V, 12 V, or 24 V input and output voltages of 5, 9, 12, or 15 VDC. This is complemented by precise load regulation (±0.5 % typical from no load to full load) and a temperature coefficient of only ±0.02 %/°C.

Designed for reliable continuous operation, the series operates stably across a temperature range of -40 °C to +85 °C (with derating from 85 °C) and is equipped with self-recovering short-circuit protection in hiccup mode. The typical isolation capacitance of 60 pF reduces capacitive coupling and is a key factor in designs with galvanically isolated measurement paths or patient circuits. The converter follows the international standard pin-out and is housed in a non-conductive, flame-retardant black plastic case. The series is fully RoHS-compliant.

In medical equipment, the 2S12B_10RP series is particularly well suited for defibrillators, electrosurgery and HF-surgery generators, and for the control and measurement electronics in X-ray systems. Beyond medical, the series is a proven solution for industrial instrumentation with high common-mode levels, high-voltage measurement systems, and test & measurement equipment — wherever outstanding isolation is required in a compact form factor.

10DPMW4_6R and 20DBMW4_6 series — 4:1 input range, reinforced 5,000 VAC isolation, and comprehensive protection

10 / 20 W Output Power

90 %Efficiency

4:1 Input Range

5,000 VAC Isolation (I/O)

DIP Package

With the new 10DPMW4_6R series (10 Watt) and 20DBMW4_6 series (20 Watt), GAPTEC Electronic is expanding its portfolio with two fully isolated, regulated DC-DC converters in a robust DIP package — tailored to the requirements of industrial, medical, and communications applications where safety, efficiency, and protection features are equally critical.

Both series cover a wide input voltage range with a 4:1 ratio and are available in 12 V, 24 V, and 48 V input versions (10 W: 12/24/48 V; 20 W: 24/48 V). Output voltages include 5, 12, and 15 V as single-output variants, as well as ±5, ±12, and ±15 V as dual-output variants — with efficiencies of up to 89 % (10 W) and 90 % (20 W).

The series provide an isolation voltage of 5,000 VAC and reinforced isolation for a working voltage of 250 Vrms — a design that securely addresses typical medical and industrial safety requirements, including those of IEC/EN/UL 62368-1. The low isolation capacitance of 17 pF reduces common-mode coupling and therefore relaxes the EMC requirements at the system level.

A comprehensive integrated protection concept safeguards the system even under fault conditions: overvoltage protection (OVP), overload protection (OCP), short-circuit protection with hiccup behaviour and automatic recovery (SCP), and undervoltage protection (UVP); the 20DBMW4_6 series additionally provides overtemperature protection (OTP). A remote on/off input and a trim function (±10 % output voltage) enable flexible system integration. Both series operate across an extended temperature range from -40 °C to +100 °C, meet EN 55032 without external components (Criterion A), and offer high immunity (ESD air ±15 kV, contact ±8 kV).

In medical equipment, the series are particularly well suited for patient monitors (multi-parameter and telemetry), for ventilators and anaesthesia workstations, and for infusion and syringe pumps; further typical fields include dialysis machines and imaging systems. Beyond medical, they address industrial control and automation systems, telecommunications and network infrastructure, and distributed power architectures.

40 W DC-DC converter with 4:1 ultra-wide input range and 1.5 kVDC isolation in a DIP package

The new 40DMW4_1.5R series is an isolated, regulated DC/DC converter with 40 W output power,
developed for demanding industrial applications that require a wide input voltage range, galvanic isolation and high reliability in equal measure. With its 4:1 ultra-wide input, the series reliably covers two nominal voltage ranges: 9–36 VDC (24 V nominal) and 18–75 VDC (48 V nominal). The single-output versions are available with regulated output voltages of 3.3 / 5 / 12 / 15 / 24 and 28 VDC.

With an efficiency of up to 92 % at full load, the series minimises power dissipation and operates entirely on free-air convection cooling — no external heat sink is required. The rugged aluminium-alloy case measures a compact 25.4 x 25.4 x 12.0 mm on the standard DIP grid (2.54 mm) and weighs only 21 g. The six-pin layout (GND, Vin, +Vo, Trim, –Vo, Ctrl), with trim function (±10 %) and remote on/off input (Ctrl), noticeably simplifies integration.

For use in harsh environments, the 40DMW4_1.5R series is rated for an extended temperature range of –40 to +105 °C (with derating). A comprehensive protection concept — input under-voltage protection, continuous short-circuit protection with automatic recovery, over-voltage protection (110–140 %) and over-current protection (110–140 %) — reliably safeguards the downstream system even in the event of a fault. The galvanic isolation of 1,500 VDC between input and output ensures a high level of operational safety; the MTBF of 1,000,000 hours (MIL-HDBK-217F @ 25 °C) underlines the long-term reliability of the series.

With a typical switching frequency of 330 kHz, a PI input filter and a ripple & noise of typ. 100 mVp-p, the
series delivers a clean, stable supply for the downstream electronics. The modules comply with the EMC
requirements of EN 55032 / FCC Part 15 Class B (CE & RE) as well as extensive immunity requirements —
including ESD ±8 kV (air) and ±6 kV (contact) per EN 61000-4-2, EFT/burst ±2 kV (EN 61000-4-4) and surge ±1 kV (EN 61000-4-5).

With its combination of ultra-wide input, galvanic isolation, high efficiency and industrial ruggedness, the
40DMW4_1.5R series is ideally suited to industrial automation, railway and transportation technology,
measurement and control technology, distributed power-supply systems and applications in harsh operating environments.
