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 (0.5A 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.
