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

? Compensates for external component temperature variations

? Very accurate IC parameter tolerances using test trimming technology

? Frequency jittering greatly reduces EMI filter cost

? Programmable switching frequency up to 85 kHz to reduce transformer

size

? Minimum operation frequency fixed to improve transient load

response

Advanced Protection/Safety Features

? Auto-restart protection reduces power delivered by >90 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 with no added

components

? No-load consumption at 230 VAC input with bias winding <10 mW for

LNK64x4-LNK64x6 and <30 mW for LNK64x7-LNK64x8

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

– ideal for CEC 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, etc.
