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 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.
