SI9120 General 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, enough to supply 30 W of output power at 100 kHz. These devices, when combined with an output MOSFET and transformer, can be used to implement single-ended power converter topologies (i.e., flyback and forward).
The Si9120 is available in both standard and lead (Pb)-free 16-pin plastic DIP and SOIC packages which are specified to operate over the industrial temperature range of −40to85.
