STR6A168HV

Package Image

Package:DIP8 (Pin 6 Removed)

TheSTR6A168HV is a power IC 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): 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): Latched shutdown or auto-restart
      Thermal Shutdown (TSD): Latched shutdown or auto-restart* 
      *With hysteresis
