UCC28221, 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
UCC28221 Features
* 1 2-MHz High-Frequency Oscillator With 1-MHz Operation Per Channel
* Matched Internal Slope Compensation Circuits
* Programmable Maximum Duty Cycle Clamp 60% to 90% Per Channel
* Peak Current Mode Control With Cycle-by-Cycle Current Limit
* Current Sense Disc
