STR3A475HDL Datasheet (Sanken) - Off-line PWM Controllers

STR3A475HDL, Off-line PWM Controllers

The STR3A475HDL is power IC 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.

STR3A475HDL Features

* Bare Lead Frame: Pb-free (RoHS Compliant)

* Low Thermal Resistance Package

* Improving circuit efficiency (Since the step drive control can keep VRM of secondary rectification diodes low, the circuit efficiency can be improved by low VF)

* Noise Reduction

* Current Mode Type PW
