2) Connect the positive terminal of the VIN power sup-
3) Set the VIN power supply to 12V and enable its
4) Verify that both WLED strings are lit.
The MAX8790A EV kit is a high-efficiency WLED driver
that utilizes a step-up DC-DC converter optimized to gen-
erate the necessary output voltage for driving six strings
of WLEDs. The EV kit is powered by a 7V to 21V input
power supply and can be configured to provide a fixed
20mA or adjustable 15mA to 25mA full-scale LED current.
