UCC28C40-Q1 Description
The UCC28C4x-Q1 family devices are high performance current-mode PWM controllers. The UCC28C4x-Q1 family supports a fixedfrequency, peak current-mode flyback implementation with UVLO and maximum duty-cycle limit options. UCC28C4X-Q1 can be configured with either primary-side regulation using an auxiliary winding or secondary-side regulation with the use of an optocoupler.
