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 • 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 <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 field reliability + Wide-Range High-Voltage D DC Input TinySwitch-III S EN/UV BP/M Figure 1.
