F6456S - Integrated Switcher

Datasheet Summary

Description

Note 1: The Pout (W) represents the thermal rating at Quasi-Resonant Operation, and the peak power output is obtained by approximately 120 to 140% of the above listed.

When the output voltage is low and ONduty is narrow, the Pout (W) shall become lower than that of above.

Features

  • Oscillator is provided on the monolithic control with adopting On-ChipTrimming technology.
  • Small temperature characteristics variation by adopting a comparator to compensate for temperature on the control part.
  • Low start-up circuit current (100uA max).
  • Built-in Active Low-Pass Filter for stabilizing the operation in case of light load.
  • Avalanche energy guaranteed MOSFET with high VDSS.
  • The built-in power MOSFET simplifies the surge absorpt.
