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 power consumption to less than 10 mW.
A push-pull output drive...
