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 Over
voltage Protection (OVP): Latched shutdown or auto-restart Thermal Shutdown (TSD): Latched shutdown or autorestart* *With hysteresis
