Power stage reference design for <100-VIN DC/DC converters

Description

This reference design implements a high frequency power stage design based on the UCC27282 120-V half-bridge MOSFET driver and CSD19531 100-V power MOSFETs. With efficient switches and flexible VGS operating range: this design can reduce overall gate drive and conduction losses to achieve optimum efficiency. This power stage design can be widely applied to many space-constrained applications such as telecom brick power modules: solar inverters and DC motor drives.

Features
  • Compact 100-V power stage design with switching up to 1MHzIndependent PWM inputs for high side and low side with cross conduction protectionLow propagation delay of 16ns: delay matching of 1ns typicalDriver VDD operating range 6 V to 16 VNegative voltage capability tolerates high noise environmentsEnable with low standby current
