General Description

The MAX16833 evaluation kit (EV kit) provides a proven

design to evaluate the MAX16833 high-voltage HB LED

driver with integrated high-side current sense. The EV

kit is set up for boost and buck-boost configurations

and operates from a 5V to 18V DC supply voltage. The

EV kit is configured to deliver up to 1A to one string of

LEDs. The total voltage of the string can vary from 3V to

36V. The anode of the LED string should be connected

to the LED+ terminal. The cathode of the LED string can

be connected either to the PGND (boost mode) or LED-

(buck-boost mode) terminal. In the case of the boost

mode, the input voltage should not exceed the LED

string voltage.

The EV kit PCB comes with a MAX16833AUE+ installed,

which is the frequency-dithering version. The EV kit also

comes with the pin-compatible MAX16833BAUE+, which

is the reference-voltage output version.
