TNY280P

TNY274-280 ® TinySwitch-III Family 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 • 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 • Improved auto-restart delivers
