The MAX16803EVKIT+BJT (EV kit) demonstrates a
high-current LED driver with accurate current control
based on the MAX16803 current regulator. This EV kit is
capable of supplying regulated LED currents of up to
1A and can operate at supply voltages between 6.5V to
40V, and temperatures ranging from 0°C to +70°C.
The MAX16803EVKIT+BJT features pulse-width modu-
lation (PWM) dimming control, user-selectable three-
level output-current setting, and a 5V-regulated output,
which can supply up to 4mA of output current. The
MAX16803EVKIT+BJT EV kit is a fully assembled and
tested printed-circuit board (PCB).
Warning : Under severe fault or failure conditions, this
EV kit can dissipate large amounts of power. Operate
this EV kit with care to avoid possible personal injury.
