UCC21220
Overview
The UCC21220 and UCC21220A devices are basic and functional isolated dual-channel gate drivers with 4A peak-source and 6A peak-sink current. They are designed to drive power MOSFETs and GaNFETs in PFC, Isolated DC/DC, and synchronous rectification applications, with fast switching performance and robust ground bounce protection through greater than 100V/ns common-mode transient immunity (CMTI).
