Part Overview
Description
The UCC3975/6/7 family of 8-pin PZT controllers integrates the necessary circuitry for operating a PZT-based backlight supply using a flyback, half-bridge, or push-pull topology. The choice of power topology depends on application requirements such as input voltage, lamp voltage, and PZT gain.
Features
3-V to 13.5-V Operation
Supports Flyback (UCC3975), Half-Bridge (UCC3976), and Push-Pull (UCC3977) Topologies
Programmable Voltage Controlled Oscillator
Open Lamp Protection: Low Shutdown Current (15-μA Typical)
Dual MOSFET Drivers
8-Pin TSSOP package
Applications
Notebook Computers
Portable Electronics Displays
