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
