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 driver provides high-speed switching for
MOSPOWER devices large enough to supply 50 W of output
power. When combined with an output MOSFET and
transformer, the Si9110/9111 can be used to implement
single-ended power converter topologies (i.e., flyback,
forward, and cuk).
The Si9110/9111 are available in both standard and
lead (Pb)-free 14-pin plastic DIP and SOIC packages which
are specified to operate over the industrial temperature range
of
40
C to 85
C.
