Overview

DATA SHEET www.onsemi.com Quasi-Resonant Current-Mode Controller for High-Power Universal Off-Line Supplies NCP1380 The NCP1380 hosts a high−performance circuitry aimed to powering quasi−resonant converters.

Capitalizing on a proprietary valley−lockout system, the controller shifts gears and reduces the switching frequency as the power loading becomes lighter.

This results in a stable operation despite switching events always occurring in the drain−source valley.

Key Features

  • a pin to implement either a combined overvoltage / overtemperature protection (Version A and B) or a combined brown.
  • out/overvoltage protection (Version C and D). Features.
  • Quasi.
  • Resonant Peak Current.
  • Mode Control Operation.
  • Valley Switching Operation with Valley.
  • Lockout for Noise.
  • Immune Operation.
  • Frequency Foldback at Light Load to Improve the Light Load Efficiency.
  • Adjustable Over Power Protection.
  • Auto.
