Primary Side Regulation
Off-Line PWM Controllers with Integrated Power MOSFET
STR5A100D Series
General Descriptions
The STR5A100D series is power IC with primary side
regulation for switching power supplies, incorporating a
sense MOSFET and a current mode PWM controller IC.
Employing the Primary Side Regulation, the product
achieves power supply systems with few external
components. Including a startup circuit and a standby
function in the controller, the product achieves the low
standby power by the automatic switching between the
PWM operation in normal operation and the
burst-oscillation under light load conditions. The rich set
of protection features helps to realize low component
counts, and high performance-to-cost power supply.

* The EI-16 core of transformer is assumed. 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.
