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.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation
of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect device reliability.
