functional block diagram
The UCC397x family of controllers contain an error amplifier whose output is preconditioned at startup, a
precision window comparator used to form the VCO, and dual MOSFET drivers customized for half-bridge or
push-pull operation. The part includes a frequency lock retry circuit, low current shutdown, and open lamp fault
protection.
