LNK616GG-TL集成電路（IC）的ACDC轉換器離線開關規(guī)格書PDF中文資料

Dramatically Simplifies CV/CC Converters

? Eliminates optocoupler and all secondary CV/CC control circuitry

? Eliminates all control loop compensation circuitry

Advanced Performance Features

? Compensates for transformer inductance tolerances

? Compensates for input line voltage variations

? Compensates for cable voltage drop (LNK61X series)

? Compensates for external component temperature variations

? Very tight IC parameter tolerances using proprietary trimming

technology

? Frequency jittering greatly reduces EMI filter cost

? Even tighter output tolerances achievable with external resistor

selection/trimming

? Programmable switching frequency up to 85 kHz to reduce transformer

size

Advanced Protection/Safety Features

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

short-circuit and control loop faults (open and shorted components)

? Hysteretic thermal shutdown – automatic recovery reduces power

supply returns from the field

? Meets high-voltage creepage requirements between DRAIN and all

other pins both on the PCB and at the package

EcoSmart?– Energy Efficient

? Easily meets all global energy efficiency regulations

? No-load consumption below 30 mW at 230 VAC with optional

external bias winding

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

– ideal for CEC and ENERGY STAR 2.0 regulations

? No current sense resistors – maximizes efficiency

Green Package

? Halogen free and RoHS compliant package

Applications

? Chargers for cell/cordless phones, PDAs, MP3/portable audio

devices, adapters, LED drivers, etc.
