Bias supply evaluation board provides a 12 V output at up to 0.5 A from a 120 V DC to 440 V DC input. The design uses an ICE5QSAG quasi-resonant flyback controller with a 950 V CoolMOS P7 IPU95R3K7P7 MOSFET in a snubberless flyback topology. The board is intended for auxiliary power in server, telecom, and industrial power systems. It operates over a -25 °C to 50 °C ambient range and measures 31.2 mm by 35.1 mm by 14.7 mm.
