Overview
LNK603-606/613-616 LinkSwitch-II Family Energy-Efficient, Accurate CV/CC Switcher for Adapters and Chargers Product Highlights 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 trans- former 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.
Description The LinkSwitch™-II dramatically simplifies low power CV/CC charger designs by eliminating an optocoupler and secondary control circuitry.
The device introduces a revolutionary control technique to provide very tight output voltage and current regulation, compens...
