Off-Line PWM Controllers with Integrated Power MOSFET STR4A100 Series Data Sheet Description The STR4A100 series are power ICs for switching power supplies, incorporating a sense MOSFET and a current mode PWM controller IC. The low standby power is acplished by the automatic switching between the PWM operation in normal operation and the burst-oscillation under light load conditions. The product achieves high cost-performance power supply systems with few external ponents. Features - Current Mode Type PWM Control - Auto Standby Function No Load Power Consumption < 10 m W - Operation Mode Normal Operation: PWM Mode Standby : Burst Oscillation Mode - Random Switching Function - Slope pensation Function - Leading Edge Blanking Function - Bias Assist Function - Soft Start Function - Protections - Overcurrent Protection (OCP) : Pulse-by-Pulse, built-in pensation circuit to minimize OCP point variation on AC input voltage - Overload Protection (OLP) : Aauto-restart - Overvoltage Protection (OVP) : Auto-restart - Thermal Shutdown (TSD) : Auto-restart with hysteresis Typical Application BR1 VAC C1 U1 STR4A100 S/GND 5 S/GND 6 S/GND...
