STR6A169HVD

The STR6A100MV/HVD 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, 100 kHz
        Green-Mode, 25 kHz to 100 kHz
        Burst Oscillation Mode
    ● Random Switching Function
    ● Slope Compensation Function
    ● Leading Edge Blanking Function
    ● Bias Assist Function
    ● Protections
        Overcurrent Protection (OCP): Pulse-by-Pulse
        Overload Protection with Timer (OLP): Auto-restart
        Overvoltage Protection (OVP): Auto-restart
        Thermal Shutdown (TSD): Auto-restart
