OZ9972A datasheet tv controller


OZ9972 / OZ9972A are high performance, Pulse Width Modulation (PWM) controllers designed for large-size LCD TV applications requiring multiple lamps. They achieve high efficiency power conversion with minimal switching loss in a PWM, full-bridge, N-Channel MOSFET topology.

0Z9972/ 0Z9972A provide high drive capability, support a wide input range, and provide a constant, user-defined operating frequency.
