Features
  • Current Mode Type PWM Control
  • 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)
  • Automatically changed operation mode in response to load conditions
  • Fixed switching frequency mode, 65 kHz (typ.)
  • Green mode, 30 kHz (typ.) to 65 kHz (typ.)
  • Burst oscillation mode
  • No Load Power Consumption, PIN < 30 mW
  • Soft Start Function
  • Random Switching Function
  • Slope Compensation Function
  • (Subharmonic Oscillation Prevention)
  • Leading Edge Blanking Function
  • Bias Assist Function

The STR3W424MXD is power IC for switching power supplies, incorporating a power MOSFET and a current mode PWM controller 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.
