Quick Start
The MAX1698 EV kit is fully assembled and tested.
Follow these steps to verify board operation.
Do not
turn on the power supply until all connections are
completed.
General Description
The MAX1698 evaluation kit (EV kit) is a fully assembled
and tested circuit board that contains a boost switch-
ing-regulator current source and array of white LEDs.
As configured, the circuit is set up to drive 3 banks of 3
series LED arrays at 20mA each; however, a wide vari-
ety of other configurations are possible. The IC can be
powered from a separate +2.7VDC to +5.5VDC input,
while LED power has a wider input range and can be
supplied either from a logic supply or battery source.
The MAX1698 features digital soft-start and adjustable
lossless LED current control. The MAX1698 EV kit
demonstrates low quiescent current, open-circuit pro-
tection, and up to 90% efficiency for maximum battery
life. Operation up to 500kHz allows the use of tiny sur-
face-mount components.
