The STR6S161HXD is power IC for switching power supplies, incorporating a power MOSFET and a current mode PWM controll IC. The operation mode is automatically changed, in response to load, to the fixed switching frequency, to the switching frequency control, and to the burst oscillation mode. Thus, the power efficiency is improved. 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
    • AC Input Voltage Detection Function
      Overvoltage Protection Function (HVP)
      Brown-In and Brown-Out Function
    • No Load Power Consumption, PIN < 40 mW
    • Automatically changed operation mode in response to load conditions
      Fixed switching frequency mode, 100 kHz (typ.) in normal operation.
      Green mode, 25 kHz (typ.) to 100 kHz (typ.) in middle to light load.
      Burst oscillation mode in light load.
    • Random Switching Function
    • Slope Compensation Function
    • Leading Edge Blanking Function
    • Bias Assist Function
    • Protections
      Two Types of Overcurrent Protection (OCP): Pulse-by-Pulse, built-in compensation circuit to minimize OCP point variation on AC input voltage
      Overload Protection with timer (OLP): Auto-restart
      Overvoltage Protection (OVP): Auto-restart
      Thermal Shutdown (TSD): Auto-restart
