STR3A253 - Off-Line PWM Controllers

This page provides the datasheet information for the STR3A253, a member of the STR3A200 Off-Line PWM Controllers family.

Datasheet Summary

Description

The STR3A200 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.

Features

  • Low Thermal Resistance Package.
  • Current Mode Type PWM Control.
  • Soft Start Function.
  • Auto Standby Function No Load Power Consumption < 15mW.
  • Operation Mode Normal Operation: PWM Mode Standby : Burst Oscillation Mode.
  • Random Switching Function.
  • Slope Compensation Function.
  • Leading Edge Blanking Function.
  • Bias Assist Function.
  • Protections.
  • Two Types of Overcurrent Protection (OCP) : Pulse-by-Pulse, built-in compensation circuit to minimize.
