Maxim Integrated MAX16834 Evaluation Kit MAX16834EVKIT+ MAX16834EVKIT+ Data Sheet

The MAX16834 evaluation (EV kit) is a fully assembled
and tested surface-mount PCB designed to evaluate
the MAX16834 pulse-width modulated (PWM) HB LED
driver controller in a step-up (boost) configuration and
optional step-up/step-down (buck-boost) operation.

The MAX16834 EV kit operates from a DC supply voltage
of 7V to 28V and requires up to 5A. The MAX16834 EV kit
circuit is configured to deliver up to 1A of current into
series LEDs with a maximum forward voltage of 28V.

The MAX16834 EV kit features two different types of
dimming control using either an analog linear input volt-
age or digital PWM input signal to control the LED
brightness. This EV kit has an undervoltage lockout
(UVLO) feature that disables the EV kit and overvoltage
protection that protects the circuit under no-load condi-
tions. The EV kit also features a FLT PCB pad to monitor
for open or short-circuit LED conditions at the LED+
and LED- PCB pads. The MAX16834 EV kit is a fully
assembled and tested surface-mount board.
