Lowest System Cost with Zero Standby

(1 mW Output Power)

• Automatically enters low consumption power-down mode when load

drops below ~0.2 of full load for LNK576 and ~0.6 for LNK574

• Detects load reconnection and automatically restarts regulation

• Simple upgrade to existing LinkSwitch-LP designs

• Very accurate IC parameter tolerances improve system manufacturing

yield

• Suitable for low-cost clampless designs

• Frequency jittering greatly reduces EMI filter cost

• Extended package creepage improves system field reliability

Advanced Protection/Safety Features

• Accurate hysteretic thermal shutdown protection – automatic

recovery reduces field returns

• Universal input range allows worldwide operation

• Auto-restart reduces delivered power by >85 during short-circuit

and open-loop fault conditions

• Simple ON/OFF control, no loop compensation needed

• High bandwidth provides excellent transient load response with no

overshoot

EcoSmart™– Energy Efficient

• No-load or standby (1 mW output power) consumption as low as

<5 mW at 230 VAC input (Note 1)

• Easily meets all global energy efficiency regulations with no added

components

• ON/OFF control provides constant efficiency to very light loads

Applications

• Chargers for cell/cordless phones, PDAs, power tools, MP3/portable

audio devices, shavers, etc.

• Standby power supply for TV, video displays, and appliances
