TNY275PN 10W Off-line Switcher 85-265VAC 700V MOSFET 132kHz DIP-8 -40°C to +150

Product Specification

TNY275PN

Enhanced Safety and Reliability Features

• Accurate hysteretic thermal shutdown protection with automatic recovery eliminates need for manual reset

• Improved auto-restart delivers <3% of maximum power in short-circuit and open loop fault conditions

• Output overvoltage shutdown with optional Zener

• Line undervoltage detect threshold set using a single optional resistor

• Very low component count enhances reliability and enables single-sided printed circuit board layout

• High bandwidth provides fast turn on with no overshoot and excellent transient load response

• Extended creepage between DRAIN and all other pins improves f ield reliability

Lowest System Cost with Enhanced Flexibility

• Simple ON/OFF control, no loop compensation needed

• Selectable current limit through BP/M capacitor value

• Higher current limit extends peak power or, in open frame applications, maximum continuous power

• Lower current limit improves efficiency in enclosed adapters/chargers

• Allows optimum TinySwitch-III choice by swapping devices with no other circuit redesign

• Tight I2f parameter tolerance reduces system cost

• Maximizes MOSFET and magnetics power delivery

• Minimizes max overload power, reducing cost of transformer, primary clamp & secondary components

• ON-time extension – extends low line regulation range/hold-up time to reduce input bulk capacitance

• Self-biased: no bias winding or bias components

• Frequency jittering reduces EMI filter costs

• Pin-out simplifies heatsinking to the PCB

• SOURCE pins are electrically quiet for low EMI

Applications

• Chargers/adapters for cell/cordless phones, PDAs, digital cameras, MP3/portable audio, shavers, etc.

• PC Standby and other auxiliary supplies

• DVD/PVR and other low power set top decoders

• Supplies for appliances, industrial systems, metering, etc.

Description

TinySwitch™-III incorporates a 700 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.
