MAXIM MAX1583 Manual
Update: 30 September, 2023
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 pro- vide 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: shut- down mode (0.5µA max), movie mode for high-efficien- cy 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 program- mable up to 300mA (100mA with installed compo- nents). A pushbutton pulse generator is installed to sim- ulate a 30ms flash pulse. The MAX1583 comes with the MAX1583X (1A current limit) installed, but the entire MAX1583 family can be eval- uated with this EV kit with minor component changes.
