Product Highlights
Cost Effective Linear/RCC Replacement
Lowest cost, component count, constant voltage, constant
current (CV/CC) solution
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
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
Controlled current in CC region provides inherent soft-start
Optional opto feedback improves output voltage accuracy
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 auxilliary supplies
Description
LinkSwitch
is specifically 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
efficiency.
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 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 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.
