The MAX16832C EV kit is configured 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-supplied 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 assembled 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 in the full data sheet.
