TNY378PN - Off-Line Switcher

This page provides the datasheet information for the TNY378PN, a member of the TNY375-380 Off-Line Switcher family.

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.

Features

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