LinkSwitch Family

Energy Efﬁcient, CV/CC Switcher for

Very Low Cost Chargers and Adapters

Product Highlights

LinkSwitch

Cost Effective Linear/RCC Replacement

•

Lowest cost and component count, constant voltage,

constant current (CV/CC) solution

Wide Range

HV DC Input

Output

(V_O)

•

Extremely simple circuit conﬁguration

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

3 W output with EE13 core for low cost and small size

•

Universal input range allows worldwide operation

Up to 70% reduction in power dissipation – reduces

enclosure size signiﬁcantly

*Estimated tolerance achievable in high volume production

including transformer and other component tolerances.

**See Optional Secondary Feedback section.

•

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

• 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

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 efﬁciency 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 inless thanone year. LinkSwitchintegratesa 700Vpower

MOSFET, PWM control, high voltage start-up, current limit,

and thermal shutdown circuitry, onto a monolithic IC.

Description

LinkSwitch is speciﬁcally designed to replace all linear

transformer/RCC chargers and adapters in the ≤3 W universal

rangeatequalorlowersystemcostwithmuchhigherperformance

and energy efﬁciency. LinkSwitch introduces a revolutionary

topology for the design of low power switching power supplies
