Evaluation Kits (1)
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 device's 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 a 30ms flash pulse.
The EV kit comes with the MAX1583X (1A current limit) installed, but the entire MAX1583 family can be evaluated with minor component changes.
