Optimized for Lowest System Cost

? Proprietary IC trimming and transformer construction

techniques enable Clampless? designs with LNK362

for lower system cost, component count and higher

efficiency

? Fully integrated auto-restart for short-circuit and

open loop protection

? Self-biased supply – saves transformer auxiliary

winding and associated bias supply components

? Frequency jittering greatly reduces EMI

? Meets HV creepage requirements between DRAIN and

all other pins both on the PCB and at the package

? Lowest component count switcher solution

Features Superior to Linear/RCC

? Accurate hysteretic thermal shutdown protection –

automatic recovery improves field reliability

? Universal input range allows worldwide operation

? Simple ON/OFF control, no loop compensation

needed

? Eliminates bias winding – simpler, lower cost

transformer

? Very low component count – higher reliability and

single side printed circuit board

? Auto-restart reduces delivered power by 95 during

short-circuit and open loop fault conditions

? High bandwidth provides fast turn-on with no

overshoot and excellent transient load response

EcoSmart?– Extremely Energy-Efficient

? Easily meets all global energy efficiency regulations

with no added components

? No-load consumption <300 mW without bias winding

at 265 VAC input (<50 mW with bias winding)

? ON/OFF control provides constant efficiency to very

light loads – ideal for mandatory CEC regulations

Applications

? Chargers/adapters for cell/cordless phones, PDAs,

digital cameras, MP3/portable audio players, and

shavers

? Supplies for appliances, industrial systems, and

metering
