Features

  • ・Low Thermal Resistance Package
    ・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
    ・Auto Standby Function
    　No Load Power Consumption < 15mW
    ・Operation Mode
    　Normal Operation: PWM Mode
    　Light Load Operation: Green-Mode
    　Standby: 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 (OLP): Auto-restart
    　Overvoltage Protection (OVP): Auto-restart
    　Thermal Shutdown (TSD): Auto-restart with hysteresis
