STR3A400

Off-Line PWM Controllers

STR3A400 Features

* 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)

* Current Mode Type PWM Control

* Soft Start Function

* Automatic Standby Function N

STR3A400 General Description

The STR3A400 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 produ.
