Overview
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 accomplished 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 components.
Features ● Current Mode Type PWM Control ● Auto Standby Function No Load Power Consumption < 10 mW ● Operation Mode Normal Operation: PWM Mode Standby : 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 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 VAC BR1 C1 U1 STR4A100 S/GND 5 S/GND 6 S/GND 7 S/GND 8 D/ST 4 VCC 2 FB/OLP 1 C3 D51 T1 C5 R1 P D1 C51 S D2 R2 L2 R54 PC1 R51 R55 R52 C52 R53 U51 R56 C2 PC1 D C6 VOUT (+) C53 (-) Package DIP8 SOIC8 Not to Scale Lineup ● Electrical Characteristics VD/ST(max.
