DESCRIPTION
The Si9112 is a BiC/DMOS integrated circuit designed for use
in high-efficiency switchmode power converters. Ahigh-voltage DMOS input allows this controller to work over a
wide range of input voltages (9- to 80-VDC). Current-modePWM control circuitry is implemented in CMOS to reduceinternal power consumption to less than 10 mW.
A CMOS output driver provides high-speed switching ofMOSPOWER devices large enough to supply 50 W of output
power. When combined with an output MOSFET and
transformer, the Si9112 can be used to implementsingle-ended power converter topologies (i.e., flyback,
forward, and cuk).
The Si9112 is available in both standard and lead (Pb)-free
14-pin plastic DIP and SOIC packages which are specified tooperate over the industrial temperature range of −40 �C to
85 �C. COMP DISCHARGE
