High-Voltage Switchmode Controller
FEATURES
9- to 80-V Input Range
Current-Mode Control
High-Speed, Source-Sink Output Drive
DESCRIPTION
The Si9112 is a BiC/DMOS integrated circuit designed for use
in high-efficiency switchmode power converters. A high-
voltage DMOS input allows this controller to work over a wide
range of input voltages (9- to 80-VDC). Current-mode PWM
control circuitry is implemented in CMOS to reduce internal
power consumption to less than 10 mW.
A CMOS output driver provides high-speed switching of
MOSPOWER devices large enough to supply 50 W of output
power. When combined with an output MOSFET and
transformer, the Si9112 can be used to implement single-
ended power converter topologies (i.e., flyback, forward, and
cuk).
The Si9112 is available in 14-pin plastic DIP, and SOIC
packages, and is specified over the industrial, D suffix (-40 to
85
°
C) temperature range.
