产品概述
The UCC28220D is a BiCMOS interleaved dual-channel Pulse Width Modulation (PWM) Controller 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. It has an UVLO turn-on threshold of 10 for use in 12V supplies for systems needing wider UVLO hysteresis and has 8V turn-off thresholds.
- Matched internal slope compensation circuits
- Peak current mode control with cycle-by-cycle current limit
- Current sense discharge transistor for improved noise immunity
- Accurate line under and over-voltage sense with programmable hysteresis
- Opto-coupler interface
- Programmable soft-start
- Green product and no Sb/Br
