UCC28220-Q1 General Description

The UCC28220 is a BiCMOS interleaved dual-channel PWM controller. Peak current mode control is used to ensure current sharing between the two channels. A precise maximum duty cycle clamp can be set to any value between 60% and 90% duty cycle per channel. UCC28220 has an UVLO turn-on threshold of 10 .
