Off-Line PWM Controllers with Integrated Power MOSFET
STR3A100 Series
General Descriptions
The STR3A100 series are power ICs for switching
power supplies, incorporating a MOSFET and a current
mode PWM controller IC.
The low standby power is accomplished by the
automatic switching between the PWM operation in
normal operation and the burst-oscillation under light
load conditions. The product achieves high
cost-performance power supply systems with few
external components.

* The output power is actual continues power that is measured at
50 °C ambient. The peak output power can be 120 to 140 % of
the value stated here. Core size, ON Duty, and thermal design
affect the output power. It may be less than the value stated here.
Applications
Low power AC/DC adapter
White goods
Auxiliary power supply
