MAX16840 Evaluation Kit
Evaluates: MAX16840
Component List (continued)
Component Suppliers
Note: Indicate you are using the MAX16840 when contacting these component suppliers.
Quick Start
Required Equipment
• MAX16840 EV kit
• AC or DC source
• 3 to 5 series-connected LED strings rated no less
than 500mA
• Current probe to measure the LED current
Procedure
The 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 AC or DC source to the AC1 and AC2
test-point holes.
2) Connect the LED string anode and cathode to the
LED+ and LED- test-point holes, respectively.
3) Clip the current probe across the LED+ wire to
measure the LED current.
4) Enable the power supply.
5) Measure the LED current using the current probe.
