LNK501
?
Energy Ef?cient, CV/CC Switcher for
Very Low Cost Chargers and Adapters
Product Highlights
Cost Effective Linear/RCC Replacement
? Lowest cost and component count, constant voltage,
constant current (CV/CC) solution
? Extremely simple circuit con?guration
? Up to 75% lighter power supply reduces shipping cost
? Primary based CV/CC solution eliminates 10 to 20
secondary components for low system cost
? Combined primary clamp, feedback, IC supply, and loop
compensation functions – minimizes external components
? Fully integrated auto-restart for short circuit and open
loop fault protection – saves external component costs
? 42 kHz operation simpli?es EMI ?lter design
? 3 W output with EE13 core for low cost and small size

MuchHigherPerformanceOverLinear/RCC
? Universal input range allows worldwide operation
? Up to 70% reduction in power dissipation – reduces
enclosure size signi?cantly
? CV/CC output characteristic without secondary feedback
? System level thermal and current limit protection
? Meets all single point failure requirements with only one
additional clamp capacitor
? Controlled current in CC region provides inherent soft-start
? Optional opto feedback improves output voltage accuracy
?
? Consumes <300 mW at 265 VAC input with no load
? Meets California Energy Commission (CEC), Energy
Star, and EU requirements
? No current sense resistors – maximizes ef?ciency
Applications
? Linear transformer replacement in all ≤3 W applications
? Chargers for cell phones, cordless phones, PDAs, digital
cameras, MP3/portable audio devices, shavers, etc.
? Home appliances, white goods and consumer electronics
? Constant output current LED lighting applications
? TV standby and other auxiliary supplies
Description
LinkSwitch is speci?cally designed to replace all linear
transformer/RCC chargers and adapters in the ≤3 W universal
range at equal or lower system cost with much higher performance
and energy ef?ciency. LinkSwitch introduces a revolutionary
topology for the design of low power switching power supplies

that rivals the simplicity and low cost of linear adapters, and
enables a much smaller, lighter, and attractive package when
compared with the traditional “brick.” With ef?ciency of up
to 75% at 3 W output and < 300 mW no-load consumption, a
LinkSwitch solution can save the end user enough energy
over a linear design to completely pay for the power supply
cost in less than one year. LinkSwitch integrates a 700 V power
MOSFET, PWM control, high voltage start-up, current limit,
and thermal shutdown circuitry, onto a monolithic IC.
