UCC28221 General Description

The UCC28220 and UCC28221 are a family of BiCMOS interleaved dual channel PWM controllers. 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. The UCC28220 has an .
