STR3A455D - Off-Line PWM Controllers

This page provides the datasheet information for the STR3A455D, a member of the STR3A400 Off-Line PWM Controllers family.

Datasheet Summary

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.

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 No Load Power Consumption < 15mW.
  • Operation Mode Normal Operation -----------------------------PWM Mode Light Load Operation ------------------------ Green-Mode Standby ---------------------------.
