TNY179 - Offline Switcher

Download the TNY179 datasheet PDF. This datasheet also covers the TNY177 variant, as both devices belong to the same offline switcher family and are provided as variant models within a single manufacturer datasheet.

Description

TinySwitch™-LT incorporates a 650 V power MOSFET, oscillator, high-voltage switched current source, current limit (user selectable) and thermal shutdown circuitry.

The IC family uses an ON/OFF control scheme and offers a design flexible solution with a low system cost and extended power capability.

Features

  • Accurate hysteretic thermal shutdown protection with automatic recovery eliminates need for manual reset.
  • Auto-restart delivers.
