PUC-2BG SIP7 DC/DC Converters

Flex Power Modules' PUC-BG series DC/DC converters are available in an industry-standard SIP7 package, are fully encapsulated and through-hole mounted, and provide 2 W output power. They include nominal 12 V, 15 V, and 24 V inputs and offer a selection of dual, unregulated outputs suitable for asymmetrical positive and negative gate drive voltages for a wide variety of semiconductor switches, including IGBTs, GaN, silicon, and silicon carbide MOSFETS. Unlike many similar products on the market, the PUC-BG series features 6.2 kV_DC isolation with reinforced insulation to a 250 V_AC working voltage and safety certification to IEC/EN/UL 62368-1.

The PUC-BG series is ideal for isolated high-side gate drive power and features low isolation capacitance, typically less than 6 pF, which prevents excessive circulating currents with the high dV/dt seen in typical bridge applications such as motor drives and inverters. The temperature rating of the product is -40°C to +100°C ambient with derating, and full power is available to +85°C in convection-cooled environments. This performance is enabled by a high-efficiency design typically reaching 80%. The parts require no minimum load and offer continuous short-circuit protection.
