IC revision3.3

Description

The STR4A100 series are power ICs for switchingpower supplies, incorporating a sense MOSFET and acurrent mode PWM controller IC.The low standby power is accomplished by theautomatic switching between the PWM operation innormal operation and the burst-oscillation under lightload conditions. The product achieves highcost-performance power supply systems with fewexternal components.

Features

● Current Mode Type PWM Control● Auto Standby FunctionNo Load Power Consumption < 10 mW● Operation ModeNormal Operation: PWM ModeStandby : Burst Oscillation Mode● Random Switching Function● Slope Compensation Function● Leading Edge Blanking Function● Bias Assist Function● Soft Start Function● Protections− Overcurrent Protection (OCP) : Pulse-by-Pulse,built-in compensation circuit to minimize OCP pointvariation on AC input voltage− Overload Protection (OLP) : Aauto-restart− Overvoltage Protection (OVP) : Auto-restart− Thermal Shutdown (TSD) : Auto-restart withhysteresis

Typical applications

  • Auxiliary power for Flat TVs,Other SMPS,Low power AC/DC adapter
  • White goods
  • Battery Chargers
