SI9110 General Description

The Si9110/9111 are BiC/DMOS integrated circuits designed for use as high-performance switchmode controllers. A high-voltage DMOS input allows the controller to work over a wide range of input voltages (10- to 120-VDC). Current-mode PWM control circuitry is implemented in CMOS to reduce internal pow.
