Photoﬂash Chargers with

Adjustable Input Current

and IGBT Drivers

DESCRIPTIO

The LT

3585 series are highly integrated ICs designed to

charge photoﬂash capacitors in digital and ﬁlm cameras.

A new control technique allows for the use of extremely

small transformers. Each part contains an on-chip high

voltage NPN power switch. Output voltage detection is

completely contained within the part, eliminating the need

for any discrete zener diodes or resistors. The output volt-

age can be adjusted by simply changing the turns ratio

of the transformer.

The CHRG/IADJ pin gives full control of the part to the

user. Driving CHRG/IADJ low puts the part in low power

shutdown. The CHRG/IADJ pin can also be used to reduce

the input current of the charger, useful in extending battery

life. The DONE pin indicates when the part has completed

charging.

The LT3585 series of parts are housed in tiny 3mm

2mm DFN packages.
