The new 1S5W_1.5RP series is a compact and robust 1W isolated and regulated DC-DC converter designed to deliver stable performance in demanding industrial and embedded applications. With a wide 2:1 input voltage range, the series adapts easily to fluctuating supply conditions while maintaining precise output regulation. This series is also available in a 2W and 3W version.
Despite its compact SIP5 package measuring only 12 x 11 x 7.55 mm and a lightweight design of approximately 3.1 g, the 1S5W_1.5RP series offers reliable electrical performance and reinforced protection features. It provides 1500 VDC isolation voltage and achieves efficiencies of up to 81%, supporting energy-efficient system designs without compromising stability. Engineered for dependable operation, the converter performs reliably across a wide operating temperature range from –40°C to +85°C (with derating). Comprehensive built-in protection features include input undervoltage protection, output overvoltage protection, short-circuit protection (self-recovering) and overcurrent protection, ensuring safe system behaviour even under fault conditions.
With a switching frequency of 350 kHz, low ripple and noise (typically 50 mVp-p), and low isolation capacitance of 20 pF, the series delivers stable and clean power for sensitive downstream electronics. The integrated Pi input filter further enhances input stability. The module meets CISPR32/EN55032 Class A requirements and can achieve Class B compliance with the recommended external circuit.
Designed for straightforward integration, the converter follows an industry-standard SIP5 pin configuration and is housed in a durable black plastic case. With an MTBF of 1,000,000 hours (MIL-HDBK-217F @ 25°C), the 1S5W_1.5RP series ensures long-term reliability in industrial control systems, instrumentation, communication equipment and distributed power architectures.
