TNY174-180 TinySwitch-LT Family Energy Efficient, Offline 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 heat sinking 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 • Hig.
