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 count...
