Notes:
1. Minimum continuous power in a typical non-ventilated enclosed adapter
measured at +50 °C ambient. Use of an external heatsink will increase power
capability.
2. Minimum peak power capability in any design or minimum continuous power in
an open frame design (see Key Applications Considerations).
3. Packages: P: DIP-8C, G: SMD-8C. See Part Ordering Information.
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 efciency 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 simplies 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
eld reliability
EcoSmart
– Extremely Energy Efcient
Easily meets all global energy efciency regulations
No-load <150 mW at 265 VAC without bias winding, <50 mW
with bias winding
ON/OFF control provides constant efciency down to very light
loads – ideal for mandatory CEC regulations and 1 W PC
standby requirements
Applications
Chargers/adapters for cell/cordless phones, PDAs, digital
cameras, MP3/portable audio, shavers, etc.
PC Standby and other auxiliary supplies
DVD/PVR and other low power set top decoders
Supplies for appliances, industrial systems, metering, etc.
Description
TinySwitch-III incorporates a 700 V power MOSFET, oscillator,
high voltage switched current source, current limit (user
selectable) and thermal shutdown circuitry. The IC family uses an
ON/OFF control scheme and offers a design exible solution with
a low system cost and extended power capability.
