DESCRIPTION
The Si9110/9111 are BiC/DMOS integrated circuits
designed
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.
