LNK563DG-TL集成電路（IC）的ACDC轉(zhuǎn)換器離線開關(guān)規(guī)格書PDF中文資料

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 efficiency

? 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 filter configuration

? 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 field 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 Efficiency Technology

? Easily meets all global energy efficiency regulations with no added components

? No-load consumption <150 mW at 265 VAC input

? ON/OFF control provides constant efficiency 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
