UCC3884, 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
