PUC-B series

1-2 W SIP7 High Isolation Unregulated DC/DC Converter

Flex Power Modules’ PUC-B series is a range of isolated, unregulated 1-2 W DC/DC converters suitable for the Industrial, Transportation, Telecom and Datacom markets.

Housed in an industry standard SIP7 package measuring 19.7×7.1×11.5mm (0.77×0.28×0.45in), these devices are available with fixed input voltages of 5V; 12V & 24V, and single output voltages of 3.3V; 5V; 12V and 15V, and dual output voltages of ±5V; ±12V and ±15V. They offer an input to output isolation level of 6000Vdc, and no minimum load is required for operation.

Efficiency levels are up to 85% at 24Vin/12Vout/100% load, and operating temperature range is up to -40°C to +100°C. Additional features include output short-circuit protection and safety compliance to EN/UL62368-1. MTBF is as high as 15Mhrs.
