20 A demonstration board

L6727 demonstration board realizes on a four-layer PCB a step-down DC/DC converter and

shows the operation of the device in a general purpose application. Input voltage can range

from 5 V to 12 V bus (when VCC > 5 V, R6 need to be removed). Output voltage is

programmed to 1.25 V. The voltage regulator can deliver up to 20 A output current. The

switching frequency is 300 kHz.
