TNY279GN
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 ef?ciency 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 ?lter costs
Pin-out simpli?es 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 under-voltage 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 ?eld reliability
