Overview

TopologyBuck Converter
Input voltage85-265 V
Output 116.05 V / 0.7 A
IC revision1.0

Description

The STR3A453D is a power IC for switching power supplies, incorporating a power MOSFET and a current-mode PWM controller IC.The product achieves low power consumption and low standby power by including a startup circuit and a standby function that automatically switch operation modes – PWM mode in normal operation and burst-oscillation mode under light-load conditions. Its enhanced protection functions also enable higher cost-effective power supply systems with few external components.

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
  • Auto Standby Function No Load Power Consumption < 15mW
  • Operation Mode Normal Operation: PWM Mode Light Load Operation: Green-Mode Standby: Burst Oscillation Mode
  • Random Switching Function
  • Slope Compensation Function
  • Leading Edge Blanking Function
  • Bias Assist Function
  • Protections Overcurrent Protection (OCP): Pulse-by-Pulse Overload Protection (OLP): Auto-restart Overvoltage Protection (OVP): Auto-restart Thermal Shutdown (TSD): Auto-restart with hysteresis

Typical applications

  • AC/DC adapter
  • White goods, Other SMPS
