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
