Product Overview

The TOP250YN is a 135W extended power design flexible integrated Off-line Switcher uses the same proven topology as TOPSwitch and it integrating the high voltage power MOSFET, PWM control, fault protection and other control circuitry onto a single CMOS chip. Many new functions are integrated to improve design flexibility, performance and energy efficiency. Line feed-forward with maximum duty cycle (DCMAX) reduction rejects line ripple and limits DCMAX at high line.
  • Eliminate or reduce cost of external components
  • Fully integrated soft-start for minimum stress/over-shoot
  • Externally programmable accurate current limit
  • Wider duty cycle for more power, smaller input capacitor
  • Line under-voltage detection - No turn OFF glitches
  • Line over-voltage shutdown extends line surge limit
  • Regulates to zero load without dummy loading
  • Hysteretic thermal shutdown for automatic fault recovery
  • Large thermal hysteresis prevents PC board over-heating
