MAX1583
White LED Camera-Flash Boost Converter
First 24V, White-LED, Flash/Strobe Supply for Camera Phones
|
Status
Active: In Production.
Description
The MAX1583 white LED boost converter drives up to
five white LEDs with a constant current to provide camera
flash/strobe in cell phones, PDAs, DSCs, and other
hand-held devices. The MAX1583 includes a 24V boost
converter and a high-voltage LDO current regulator for
high efficiency and long battery life. Two logic inputs
control four modes of operation: shutdown mode (0.5µA
max), movie mode for high-efficiency continuous lighting
(programmable up to 100mA), precharge mode for
charging a reservoir capacitor to 24V while the LEDs
are off (POK output indicates a full reservoir capacitor),
and strobe mode for firing the flash during an exposure
with a regulated current programmable up to 300mA.
The MAX1583X, MAX1583Y, and MAX1583Z offer high,
medium, and low current limits, respectively, to allow
tradeoff between reservoir capacitor size and peak
input current.
The MAX1583 is available in a 10-pin 3mm x 3mm
TDFN package (0.8mm max height).
