The MAX8607 evaluation kit (EV kit) is a fully assembled
and tested surface-mount printed-circuit board (PCB)
for evaluating the MAX8607 1.5A white LED flash/strobe
step-up converter IC. The EV kit accepts a 2.7V to 5.5V
input voltage and drives a Lumileds LXCL-PWF1 white
LED with up to 700mA (limited by LED current rating)
for camera flash/strobe in cell phones, PDAs, DSCs,
and other handheld devices. The MAX8607 switching
frequency is 1MHz, allowing tiny external components.
Two logic inputs control four modes of operation: shutdown
mode reduces the quiescent current to 0.1µA
(typ), movie mode supplies up to 360mA of LED current
for continuous lighting, flash mode supplies up to
700mA of LED current for short-duration lighting during
an exposure, and disco mode supplies +5V (at up to
1A) to external circuits while driving the LED with a
fixed 80mA current. Flash-mode and movie-mode LED
currents are preset to 700mA and 200mA, respectively,
in the default EV kit configuration. The EV kit also features
an on-board pushbutton pulse-generator circuit to
simulate a 600ms flash pulse for flash-mode evaluation.
Caution: The MAX8607 EV kit is capable of driving the
LED at very high brightness. Use caution when observing
LED illumination.
