Quick Start
Recommended Equipment
Before beginning, the following equipment is needed:
? 7V to 24V, 4A DC power supply
? One series-connected LED string rated at 660mA
(28V maximum LED voltage)
? One current probe to measure LED current
? One voltmeter
Procedure
The MAX16821B EV kit is fully assembled and tested.
Follow the steps below to verify board operation.
Caution: Do not turn on the power supply until all
connections are completed.
1) Connect the positive terminal of the power supply to
the VIN pad on the EV kit. Connect the negative ter-
minal of the power supply to the PGND pad next to
the VIN pad.
2) Connect the anode end of the LED string to the
LED+ pad.
3) Connect the cathode end of the LED string to the
LED- pad.
4) Clip the current probe across the string wires to
measure the LED current.
5) Turn on the power supply and increase the voltage
to 7V or above.
6) Verify that the LED string DC current is approxi-
mately 660mA.
7) Measure the voltage between the LED+ to LED-
PCB pads.
Detailed Description
The MAX16821B EV kit circuit is designed to evaluate
the MAX16821B PWM LED driver controller. The EV kit
is configured in a boost topology and provides 660mA
LED current for a string of user-supplied external high-
brightness LEDs (HBLEDs) rated up to 28V. The
MAX16821B EV kit operates from a DC supply voltage
of 7V to 28V.
The EV kit average input current is set to 3.75A using
resistor R6. The LED current is set to 660mA using resis-
tor R7. A PWMDIM PCB pad is provided for PWM dim-
ming operation of the external LEDs. A CLKOUT PCB
pad is also available to drive a second LED current regu-
lator 180° out-of-phase with the first EV kit.
