10) To improve thermal performance, use multiple layers for

GND. Place as many vias as possible to the ground plane around

the anode of the asynchronous diode.

11) The thermal pad under the A6211 must connect to the ground

plane using multiple vias. More vias will insure lower operating

temperature and higher efficiency.

12) Connection to the LED array should be kept short. Exces-

sively long wires can cause ringing or oscillation. When the LED

array is separated from the converter board and an output capaci-

tor is used, the capacitor should be placed on the converter board

to reduce the effect of stray inductance from long wires.
