UCC3884 General Description

The UCC3884 is a high performance current mode PWM controller intended for single ended switch mode power supplies. The chip implements a frequency foldback scheme that decreases the oscillator frequency as the output voltage falls below a programmed value. This technique decreases the average outpu.
