High-Voltage Switchmode Controllers
FEATURES
D 10- to 120-V Input Range
D Current-Mode Control
D High-Speed, Source-Sink Output Drive
D High Efficiency Operation (> 80%)
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.
