LNK625DG-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

Dramatically Simplifies CV Converters

? Eliminates optocoupler and all secondary CV control circuitry

? Eliminates bias winding supply – IC is self biasing

Advanced Performance Features

? Compensates for external component temperature variations

? Very tight IC parameter tolerances using proprietary trimming

technology

? Continuous and/or discontinuous mode operation for design

flexibility

? Frequency jittering greatly reduces EMI filter cost

? Even tighter output tolerances achievable with external resistor

selection/trimming

Advanced Protection/Safety Features

? Auto-restart protection reduces delivered power by >95 for

output short-circuit and all control loop faults (open and shorted

components)

? Hysteretic thermal shutdown – automatic recovery reduces power

supply returns from the field

? Meets HV creepage requirements between Drain and all other pins,

both on the PCB and at the package

EcoSmart?– Energy Efficient

? No-load consumption <200 mW at 230 VAC and down to below

70 mW with optional external bias

? Easily meets all global energy efficiency regulations with no added

components

? ON/OFF control provides constant efficiency down to very light

loads – ideal for mandatory EISA and ENERGY STAR 2.0 regulations

? No primary or secondary current sense resistors – maximizes

efficiency

Green Package

? Halogen free and RoHS compliant package

Applications

? DVD/STB

? Adapters

? Standby and auxiliary supplies

? Home appliances, white goods and consumer electronics

? Industrial controls
