STR5A162D

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.
