TNY*177P TNY177PN OFF LINE SWITCHER IC DIP-7

Energy Efficient, Off-line Switcher with Enhanced Flexibility and Extended Power Range

 

Product Highlights

Lowest System Cost with Enhanced Flexibility

·          650 V rating optimized for non-active PFC applications

·          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-LT 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

 

Enhanced Safety and Reliability Features

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

·          Auto-restart delivers <3% of maximum power in short circuit and open loop fault conditions

·          Output overvoltage shutdown with optional Zener

·          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 field reliability

 

EcoSmart® – Extremely Energy Efficient

·          Easily meets all global energy efficiency regulations

·          No-load

·          ON/OFF control provides constant efficiency down to very light loads – ideal for mandatory CEC regulations

 

Applications

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

·          DVD/PVR and other low power set top decoders

·          Supplies for appliances, industrial systems, metering, etc

 

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.
