com MAX1583 Evaluation Kit General Description The MAX1583 evaluation kit (EV kit) is a fully assembled and tested surface-mount circuit board for evaluating the MAX1583 white LED flash boost converter.
The EV kit accepts a 2.
6V to 5.
5V input voltage and drives up to five series white LEDs with a constant current to provide camera flash/strobe in cell phones, PDAs, DSCs, and other hand-held devices.
The MAX1583 switching frequency is 1MHz, allowing tiny external components.
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 (100mA with installed components).
A pushbutton pulse generator is installed to simulate ...
