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 V for use in 12-V supplies. It has 8-V turn-off threshold.

Additional features include a programmable internal slope compensation with a special circuit that ensures exactly the same slope is added to each channel. The UCC28220 is available in a 16-pin low-profile TSSOP package.
