General Description

The MAX1583 white LED boost converter drives up to

five white LEDs with a constant current to provide cam-

era 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 light-

ing (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).
