UCC2884 Datasheet (Texas Instruments) - Frequency Foldback Current Mode PWM Controller

UCC2884, Frequency Foldback Current Mode PWM Controller

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
