UCC28220 Datasheet (Texas Instruments)

UCC28220, Dual PWM Controller

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
