Overview
TNY274-280 TinySwitch-III Family Energy-Efficient, Off-Line Switcher with Enhanced Flexibility and Extended Power Range Product Highlights 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 ...
