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.

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, 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.
