产品概述
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.
