TNY377 - Off-Line Switcher

Download the TNY377 datasheet PDF. This datasheet also covers the TNY375 variant, as both devices belong to the same off-line switcher family and are provided as variant models within a single manufacturer datasheet.

General Description

TinySwitch-PK incorporates a 700 V MOSFET, oscillator, highvoltage switched current source, current limit (user selectable), and thermal shutdown circuitry.

A unique peak mode feature boosts current limit and frequency for peak load conditions.

Key Features

  • Accurate hysteretic thermal shutdown with automatic recovery provides complete system level overload protection and eliminates need for manual reset.
  • Auto-restart delivers.
