Demo Board Description
The L6911C demo board shows the operation of the device in a standard VRM 8.4 application. This evaluation
board allows voltage adjustability (1.3V - 3.5V) through the switches S1-S5 and high output current capability
(up to 14A). The device is supplied by the 12V input rail while the power conversion starts from the 5V input rail.
The device is also able to operate with a 5V supply voltage; in this case 12V input can be directly connected to
the 5V power source. The four layers demo board's copper thickness is of 70
m in order to minimize conduction
losses considering the high current that the circuit is able to deliver. Figure 10 shows the demo board's sche-
matic circuit.
