TOP250 - Integrated Off-line Switcher

This page provides the datasheet information for the TOP250, a member of the TOP247F Integrated Off-line Switcher family.

Datasheet Summary

Description

TOPSwitch-GX uses the same proven topology as TOPSwitch, cost effectively integrating the high voltage power MOSFET, PWM control, fault protection and other control circuitry onto a single CMOS chip.

Features

  • eliminate or reduce cost of external components.
  • Fully integrated soft-start for minimum stress/overshoot.
  • Externally programmable accurate current limit.
  • Wider duty cycle for more power, smaller input capacitor.
  • Separate line sense and current limit pins on Y/R/F packages.
  • Line under-voltage (UV) detection: no turn off glitches.
  • Line overvoltage (OV) shutdown extends line surge limit.
  • Line feed-forward with maximum duty cycle (DCMAX.
