LinkSwitch Family

Energy Efficient, CV or CV/CC Switcher for

Very Low Cost Adapters and Chargers

Product Highlights

LinkSwitch

Cost Effective Linear/RCC Replacement

• Lowest cost and component count, constant voltage (CV)

or constant voltage/constant current (CV/CC) solution

• Extremely simple circuit configuration

Wide Range

HV DC Input

Output

(V_O)

• 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 simplifies EMI filter design

(CV/CC)

10%

Much Higher Performance Over Linear/RCC

• Universal input range allows worldwide operation

• Up to 70% reduction in power dissipation–reduces

enclosure size significantly

• 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

EcoSmart^®- Extremely Energy Efficient

• Consumes <300 mW at 265 VAC input with no load

• Meets Blue Angel, Energy Star, and EC requirements

• No current sense resistors–maximizes efficiency

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

• TV standby and other auxiliary supplies

measured at 50 °C ambient. 2. See Figure 1 (b) for Min (CV only designs)

and Typ (CV/CC charger designs) power points identified on output

characteristic. 3. Uses higher reflected voltage transformer designs for

increased power capability – see KeyApplication Considerations section.

Description

and enables a much smaller, lighter, and attractive package when

compared with the traditional "brick". With efficiency of up to

75%and<300mWno-loadconsumption,aLinkSwitchsolution

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 700 V power MOSFET, PWM

control,highvoltagestart-up,currentlimit,andthermalshutdown

circuitry, onto a monolithic IC.

LinkSwitch is specifically designed to replace low power linear

transformer/RCC chargers and adapters at equal or lower system

costwithmuchhigherperformanceandenergyefficiency.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,
