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

dip-varnished transformer

? Programmable line undervoltage 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

? Expanded scalable device family for low system cost

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

? Simple design practically eliminates rework in manufacturing

EcoSmart?– Extremely Energy Efficient

? No load consumption <50 mW with bias winding and

<250 mW without bias winding at 265 VAC input

? Meets California Energy Commission (CEC), Energy Star, and

EU requirements

? Ideal for cell-phone charger and PC standby applications

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 improves safety
