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.

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