STR-X6750F - Power IC for Quasi-Resonant Type Switching Power Supply

General Description

The STR-X6750F 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.

Key Features

  • Quasi-resonant operation mode Achieves the optimal high efficiency and low noise power supply systems.
  • 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.
  • Input compensation at overcurrent The function reduces the distortion.
