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

LinkSwitch-LP
Energy Effi cient Off-Line Switcher IC for
Linear Transformer Replacement
trimming technology and transformer construction
techniques enable Clampless™designs – decreases
component count/system cost and increases effi ciency
protection – eliminates the thermal fuse used with linear
transformers or additional components in RCC designs
input fi lter confi guration
other pins, both on the PCB and at the package
recovery improves fi eld reliability
short circuit and open loop fault conditions
and excellent transient load response
no added components
light loads – ideal for mandatory CEC regulations
MP3/portable audio devices, shavers etc.
