STR-W6765N - Power IC for Quasi-Resonant Type Switching Power Supply

General Description

The STR-W6765N is power IC for quasi-resonant type switching power supply, incorporating a power MOSFET and a controller IC.

The product achieves high efficiency and low noise power supply systems by the quasi-resonant operation and the bottom-skip quasi-resonant operation.

Key Features

  • Multi operation mode The operation mode switching according to load conditions achieves the optimal high efficiency and low noise power supply systems across the full load range.
  • Current mode control.
  • Built-in PWM oscillator The PWM operates with the minimum frequency of around 22kHz, until the quasi-resonant signal becomes valid, reduces the stress on components at startup and load-shorted.
  • Built-in soft start function.
  • Step-drive function, reducing switching noise.
