The MAX16832C evaluation kit (EV kit) demonstrates the
MAX16832C hysteretic current-mode high-brightness
LED (HB LED) driver IC. The MAX16832C EV kit is config-
ured as a step-down topology with a constant-current HB
LED driver circuit for external HB LEDs. The MAX16832C
EV kit operates from a DC supply voltage of 6.5V to 65V
and is configured to deliver 666mA of current to user-sup-
plied HB LEDs. The output voltage for the HB LED string
can go up to 64V and depends upon the EV kit’s input
voltage.
The MAX16832C EV kit can be configured for digital
pulse-width modulation (PWM) dimming operation
using a digital PWM input signal. The EV kit circuit also
features a thermal-foldback and temperature-simulation
circuit feature. The MAX16832C EV kit is a fully assem-
bled and tested surface-mount board. Additionally, the
PCB layout design has been maximized for optimum
thermal dissipation. The MAX16832C EV kit can also
evaluate a MAX16832A after replacing the IC, which
can be ordered from the number listed below.
Warning: Voltages exceeding 42V could exist on the
LED+ and LED- output pads.
19-4289; Rev 0; 9/08
