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
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.
