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.

UCC28220 has an UVLO turn-on threshold of 10 V for use in 12-V supplies while UCC28221 has a turn-on threshold of 13 V for systems needing wider UVLO hysteresis. Both have 8-V turn-off thresholds.

Additional features include a programmable internal slope compensation with a special circuit which is used to ensure exactly the same slope is added to each channel and a high voltage 110-V internal JFET for easier startup for the wider hysteresis UCC28221 version.
