Product Highlights
Cost Effective Linear/RCC Replacement
Lowest cost and component count, constant voltage (CV)
or constant voltage/constant current (CV/CC) solution
Extremely simple circuit conguration
Up to 75% lighter power supply reduces shipping cost
PrimarybasedCV/CCsolutioneliminates10to20secondary
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 simplies EMI lter design
Much Higher Performance Over Linear/RCC
Universal input range allows worldwide operation
Upto70%reductioninpowerdissipation–reducesenclosure
size signicantly
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
EcoSmart
- Extremely Energy Efcient
Consumes <300 mW at 265 VAC input with no load
Meets Blue Angel, Energy Star, and EC requirements
No current sense resistors–maximizes efciency
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 specically designed to replace low power linear
transformer/RCCchargersandadaptersatequalorlowersystem
cost with much higher performance and energy efciency.
LNK500 is a lower cost version of the LNK501 with a wider
tolerance output CC characteristic. LinkSwitch introduces a
revolutionary patented 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

Notes: 1. Output power for designs in an enclosed adapter
measured at 50 °C ambient. 2. See Figure 1 (b) for Min (CV only
designs) and Typ (CV/CC charger designs) power points identied
on output characteristic. 3. Uses higher reected voltage transformer
designs for increased power capability – see Key Application
Considerations section. 4. For lead-free package options, see Part
Ordering Information.
attractive package when compared with the traditional “brick.”
Withefciencyofupto75%and<300mWno-loadconsumption,
a LinkSwitch solution can save the end user enough energy
over a linear design to completely pay for the full power
supply cost in less than one year. LinkSwitch integrates a
700VpowerMOSFET,PWMcontrol,highvoltagestart-up,current
limit, and thermal shutdown circuitry, onto a monolithic IC.
