3mm DFN Package
The LT
®
3484 family of photoflash capacitor charger ICs is
designed for use in digital camera and mobile phone
applications where space is at a premium. The LT3484’s
patented control technique allows it to use extremely small
transformers, and the improved NPN power switch re-
quires no external Schottky diode clamp, reducing solu-
tion size. Output voltage detection requires no external
circuitry as the transformer turns ratio determines final
charge voltage.
The devices feature a V
BAT
pin, which allows the use of 2
alkaline cells to charge the capacitor. The LT3484-0, -2
and -1 have primary current limits of 1.4A, 1A and 0.7A
respectively, resulting in tightly controlled average input
current of 500mA, 350mA and 225mA respectively. The
three versions are otherwise identical.
The CHARGE pin gives full control of the part to the user.
Driving CHARGE low puts the part in shutdown. The DONE
pin indicates when the part has completed charging. The
LT3484 series of parts are housed in a tiny low profile
