Off-Line PWM Controllers with Integrated Power MOSFET STR4A100 Series
Overview
| Topology | Forward Converter |
| Input voltage | 85-265 V |
| Switching frequency | 58-72 kHz |
| Output 1 | 5 V / 1 A |
| IC revision | 3.3 |
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
