Overview

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, compensating for transformer and internal parameter tolerances along with input voltage variations. The device incorporates a 700 V power MOSFET, a novel ON/OFF control state machine, a high voltage switched current source for self biasing, frequency jittering, cycle-by-cycle current limit and hysteretic thermal shutdown circuitry onto a monolithic IC.

Applications

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

Key features

Eliminates optocoupler and all secondary CV/CC control circuitry
Eliminates all control loop compensation circuitry
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
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
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
Halogen free and RoHS compliant package
