SI9112 General Description

The Si9112 is a BiC/DMOS integrated circuit designed for use in high-efficiency switchmode power converters. A high-voltage DMOS input allows this controller to work over a wide range of input voltages (9- to 80-VDC). Current-mode PWM control circuitry is implemented in CMOS to reduce internal power.
