Description
The LNK632DG dramatically simplifies low power CV/CC charger
designs by eliminating an optocoupler and secondary control
circuitry. The device uses an ON/OFF control technique to provide
very tight output voltage regulation, in addition to output current
control ideal for battery charging applications. The combination of
proprietary IC trimming and E-Shield
techniques enables Clampless designs with the LNK632DG when
an external bias circuit is used.
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
Enables Clampless
Compensates for cable voltage drop
Compensates for external component temperature variations
Very tight IC parameter tolerances using proprietary trimming
technology
Frequency jittering greatly reduces EMI filter cost
Auto-restart protection reduces power delivered by about 85%
for output short circuit and control loop faults (open and
shorted components)
Hysteretic thermal shutdown – automatic recovery reduces
power supply returns from the field
Easily meets all global energy efficiency regulations with no
added components
No-load consumption down to <30 mW at 230 VAC input with
bias winding
ON/OFF control provides constant efficiency down to very light
loads – ideal for EISA and ENERGY STAR regulations
No current sense resistors – maximizes efficiency
Halogen free and RoHS compliant package
Chargers for cell/cordless phones, PDAs, MP3/portable audio
devices, adapters, etc.
