SIP-7 DC/DC converters for gate drive power applications

News • March 17, 2022

The PUC-BG series includes nominal 12 V, 15 V and 24 V inputs and a selection of dual, unregulated outputs are available, 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 kVDC isolation with reinforced insulation to a 250 VAC working voltage, with 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 products 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 reaching typically 80%. The parts require no minimum load and offer continuous short circuit protection.

“Our new PUC-BG series is offered at an attractive price-point” comments George Zou, Product Manager at Flex Power Modules, “these parts are perfect in industrial applications for gate drive power, where the Flex Power Modules brand is a guarantee of fast technical support, quality and reliability”.
