AC/DC Off-Line Switcher IC DIP-8 360mA Output

The Power Integrations LinkSwitch-TN Off-Line Switcher IC is an energy-efficient solution designed to replace linear and capacitor-fed non-isolated power supplies in the under 360mA output current range. It provides enhanced performance and energy efficiency at a comparable system cost.

This device integrates a 700V power MOSFET, oscillator, simple on/off control scheme, high-voltage switched current source, frequency jittering, cycle-by-cycle current limit, and thermal shutdown circuitry onto a single monolithic IC. The start-up and operating power are derived directly from the voltage on the DRAIN pin, eliminating the need for a bias supply and associated circuitry in buck or flyback converters.

Key Features

• Supports Buck, Buck-boost, and Flyback topologies
• Fully integrated auto-restart safely limits output power during fault conditions such as short-circuit or open loop
• 66kHz operation with accurate current limit allows the use of low-cost, off-the-shelf inductors
• High breakdown voltage of 700V provides excellent input surge withstand
• Frequency jittering reduces EMI
• High thermal shutdown temperature (+135°C minimum)
• Universal input voltage range (85 to 265VAC)
• EcoSmart™ technology ensures high energy efficiency, consuming typically 50/80mW in self-powered buck topology and 7/12mW in flyback topology at no-load
• Complies with California Energy Commission (CEC), Energy Star, and EU requirements
• Pure matte tin (Pb-free) lead finish

Measuring 40mm x 30mm x 25mm and weighing just 3.629 grams, this through-hole DIP IC is suitable for a wide variety of applications.
