This reference design is a half-bridge isolated gated driver used in driving power stages of UPS, inverters, server and telecom applications. This reference design is based on the UCC21520 reinforced insulated gate driver and is capable of driving MOSFETs and SiC-FETs. The design contains a built-in isolated push-pull auxiliary power supply for powering the output of the isolated gate driver. By bringing together the isolated gate driver and isolated power supply in a compact board with a form factor (!~30 mm × 35 mm), this reference design provides a fully tested robust half-bridge driver solution capable of withstanding >100 kV/μs common-mode transient immunity (CMTI).
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
