DESCRIPTION
The Si9120 is a BiC/DMOS integrated circuit designed for use in low-power, high-efficiency off-line power supplies. High-voltage DMOS inputs allow the controller to work over a wide range of input voltages (10- to 450-VDC). Current-mode PWM control circuitry is implemented in CMOS to reduce quiescent current to less than 1.5 mA. A CMOS output driver provides high-speed switching for MOSFET devices with gate charge, Qg, up to 25 nC, ... |
