STR6A153MV

Off-Line PWM Controllers with Integrated Power MOSFET STR6A100xV/xVD Series Data Sheet Description The STR6A100xV/xVD series are power ICs for switching power supplies, incorporating a MOSFET and a current mode PWM controller IC. The operating mode of the IC automatically changes to green-mode or burst oscillation mode according to load in order to improve the all load efficiency. The product achieves high cost-performance power supply systems with few external components. Features ● 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 ● Adjustable Standby Operating Point No Load Power Consumption < 15 mW ● Operation Mode Fixed Frequency: 65 kHz / 100 kHz Green-Mode: 25 kHz to 65 kHz / 25 kHz to 100 kHz Burst Oscillation Mode ● Random Switching Function ● Slope Compensation Function ● Leading Edge Blanking Function ● Bias Assist Function ● Protections ● Two Types of Overcurrent Protection (OCP): Pulseby-Pulse, built-in compensation circuit to minimize OCP point variation on AC input voltage Overload Protection with Timer (OLP): Auto-restart Overvoltage Protection (OVP): Latched shutdown or auto-restart Thermal Shutdown (TSD): Latched shutdown or autorestart* *With hysteresis Typical Application VAC BR1 C1 ROCP C4 RBA C3 PC1 T1 D51 P U1 1 S/OCP D/ST 8 2 BA D/ST 7 3 GND 4 FB/OLP NC 5 VCC STR6A100×V D2 ...
