LinkSwitch-LP
Energy Effi cient Off-Line Switcher IC for
Linear Transformer Replacement
Product Highlights
Lowest System Cost and Advanced Safety Features
• Lowest component count switcher
• Very tight parameter tolerances using proprietary IC
trimming technology and transformer construction
techniques enable Clampless™designs – decreases
component count/system cost and increases effi ciency
• Meets industry standard requirements for thermal overload
protection – eliminates the thermal fuse used with linear
transformers or additional components in RCC designs
• Frequency jittering greatly reduces EMI – enables low cost
input fi lter confi guration
• Meets HV creepage requirements between DRAIN and all
other pins, both on the PCB and at the package
• Proprietary E-Shield™ transformer eliminates Y-capacitor
Superior Performance over Linear and RCC
• Hysteretic thermal shutdown protection – automatic
recovery improves fi eld reliability
• Universal input range allows worldwide operation
• Auto-restart reduces delivered power by >85% during
short circuit and open loop fault conditions
• Simple ON/OFF control, no loop compensation needed
• High bandwidth provides fast turn on with no overshoot
and excellent transient load response
EcoSmart
®
– Energy Effi ciency Technology
Easily meets all global energy effi ciency regulations with
no added components
• No-load consumption <150 mW at 265 VAC input
• ON/OFF control provides constant effi ciency to very
light loads – ideal for mandatory CEC regulations
Applications
Chargers for cell/cordless phones, PDAs, power tools,
MP3/portable audio devices, shavers etc.
Standby and auxiliary supplies
Description
LinkSwitch-LP switcher ICs cost effectively replace all
unregulated isolated linear transformer based (50/60 Hz) power
supplies up to 3 W output power. For worldwide operation, a
single universal input design replaces multiple linear transformer
based designs. The self-biased circuit achieves an extremely low
no-load consumption of under 150 mW. The internal oscillator
frequency is jittered to signifi cantly reduce both quasi-peak and
average EMI, minimizing fi lter cost.

Notes:
1. Output power may be limited by specifi c application parameters
including core size and Clampless operation (see Key Application
Considerations).
2. Minimum continuous power in a typical non-ventilated enclosed
adapter measured at 50 °C ambient.
3. Minimum practical continuous power in an open frame design with
adequate heat sinking, measured at 50 °C ambient.
