132kHz Power Management Chip LNK364DN Converter Offline Flyback Topology 15mA

LNK364DN Converter Offline Flyback Topology 132kHz Power management chip

Product Highlights

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
