Description
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 I2
f 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
