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

Output

•

Simple ON/OFF control, no loop compensation needed

Selectable current limit through BP/M capacitor value

Wide-Range

HV DC Input

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

EN/UV

BP/M

TinySwitch-III

PI-4095-082205

•

Tight I²f parameter tolerance reduces system cost

Figure 1. Typical Standby Application.

Maximizes MOSFET and magnetics power delivery

Minimizes max overload power, reducing cost of

transformer, primary clamp & secondary components

OUTPUT POWER TABLE

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

Table 1. 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 KeyApplication Considerations). 3. Packages:

P: DIP-8C, G: SMD-8C. See Part Ordering Information.

•

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

EcoSmart^®– Extremely Energy Efﬁcient

•

PC Standby and other auxiliary supplies

DVD/PVR and other low power set top decoders

Supplies for appliances, industrial systems, metering, etc.

•

Easily meets all global energy efﬁciency regulations

No-load <150 mW at 265 VAC without bias winding,

<50 mW with bias winding

•

ON/OFF control provides constant efﬁciency down to

very light loads – ideal for mandatory CEC regulations

and 1 W PC standby requirements

Description

TinySwitch-IIIincorporatesa700VpowerMOSFET,oscillator,

high voltage switched current source, current limit (user

selectable) and thermal shutdown circuitry. The IC family uses

anON/OFFcontrolschemeandoffersadesignﬂexiblesolution

with a low system cost and extended power capability.

Applications

•

Chargers/adapters for cell/cordless phones, PDAs, digital

cameras, MP3/portable audio, shavers, etc.
