GENERAL DESCRIPTION
OZ9972/72A are high performance, Pulse Width Modulation (PWM) controllers
designed for large-size LCD TV applications requiring multiple lamps. They achieve
high effi ciency power conversion with minimal switching loss in a PWM, full-bridge,
N-Channel MOSFET topology.
OZ9972/72A provide high drive capability, support a wide input range, and provide a
constant, user-defi ned operating frequency.
