5 A demonstration board
L6727 demonstration board realizes on a two-layer PCB a step-down DC/DC converter and
shows the operation of the device in a general-purpose low-current application. Input
voltage can range from 5 V to 12 V bus. Output voltage is programmed at 1.25 V. The
application can deliver an output current in excess of 5 A. The switching frequency is 300
kHz.
