TinySwitch-II Family

Enhanced, Energy Efficient,

Low Power Off-line Switcher

Product Highlights

TinySwitch-II Features Reduce System Cost

• Fully integrated auto-restart for short circuit and open

loop fault protection–saves external component costs

• Built-in circuitry practically eliminates audible noise with

ordinary varnished transformer

Optional

DC Output

UV Resistor

Wide-Range

HV DC Input

EN/UV

• Programmable line under-voltage detect feature prevents

power on/off glitches–saves external components

• Frequency jittering dramatically reduces EMI (~10 dB)

–minimizes EMI filter component costs

• 132 kHz operation reduces transformer size–allows use of

EF12.6 or EE13 cores for low cost and small size

• Very tight tolerances and negligible temperature variation

on key parameters eases design and lowers cost

• Lowest component count switcher solution

Better Cost/Performance over RCC & Linears

• Lower system cost than RCC, discrete PWM and other

integrated/hybrid solutions

• Cost effective replacement for bulky regulated linears

• Simple ON/OFF control–no loop compensation needed

• No bias winding–simpler, lower cost transformer

High Performance at Low Cost

• High voltage powered–ideal for charger applications

• High bandwidth provides fast turn on with no overshoot

• Current limit operation rejects line frequency ripple

• Built-in current limit and thermal protection

TinySwitch-II devices incorporate auto-restart, line under-

voltage sense, and frequency jittering. An innovative design

minimizes audio frequency components in the simple ON/OFF

control scheme to practically eliminate audible noise with

standard taped/varnished transformer construction. The fully

integrated auto-restart circuit safely limits output power during

fault conditions such as output short circuit or open loop,

reducing component count and secondary feedback circuitry

cost. An optional line sense resistor externally programs a line

Description

TinySwitch-II maintains the simplicity of the TinySwitch

topology, while providing a number of new enhancements to

further reduce system cost and component count, and to

practically eliminate audible noise. Like TinySwitch, a 700 V

powerMOSFET,oscillator,highvoltageswitchedcurrentsource,

current limit and thermal shutdown circuitry are integrated onto a

monolithic device. The start-up and operating power are derived

directly from the voltage on the DRAIN pin, eliminating the

need for a bias winding and associated circuitry. In addition, the
