LNK613PG集成电路（IC）的ACDC转换器离线开关规格书PDF中文资料

LNK613PG属于集成电路（IC）的ACDC转换器离线开关。由荷兰帕沃英蒂格盛有限公司制造生产的LNK613PGAC DC 转换器，离线开关该系列是元器件级控制产品，用于构建将交流市电转换为直流电（通常电压大幅降低）的设备。集成和未集成系统主要开关元件的器件均包括在内。由于高输入输出电压比，以及此类系统中通常需要隔离，这些器件通常与外部变压器配合使用。尽管通常使用定制变压器来实现此用途，但也有许多专门用于此用途的库存产品，请参见“开关转换器，SMPS 变压器”标题。

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.
