Off-Line PWM Controllers with Integrated Power MOSFET

STR3A400 Series

Data Sheet

Description

Package

The STR3A400 series are power ICs for switching

power supplies, incorporating a MOSFET and a current

mode PWM controller IC.

DIP8

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 product achieves high

cost-performance power supply systems with few

external components.

Lineup

Features

● Electrical Characteristics

f_OSC(AVG)(typ.) = 65 kHz

V_DSS(min.) = 650 V

● Low Thermal Resistance Package

● Improving circuit efficiency (Since the step drive

control can keep V_RMof secondary rectification

diodes low, the circuit efficiency can be improved by

low V_F)

● Protections

Two Types of Overcurrent Protection (OCP):

Pulse-by-Pulse, built-in compensation circuit to

minimize OCP point variation on AC input voltage

Overload Protection (OLP): Auto-restart

Overvoltage Protection (OVP): Latched shutdown or

auto-restart

* 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.

Thermal Shutdown (TSD): Latched shutdown or

auto-restart with hysteresis
