LNK616PG dip-7

Микросхема LNK616PG (LNK616)

LNK616PG - Energy-Efficient, Accurate CV/CC Switcher for Adapters and Chargers, DIP-7

 

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

 

Применение

• Chargers for cell/cordless phones, PDAs, MP3/portable audio devices, adapters, LED drivers, etc.
