Demonstration board description
8/23
The 5 V output is obtained from the 24 V output by means of an integrated power IC, the
L5970D. The L5970D is a step-down monolithic power switching regulator with a switch
current limit of 1 A, able to deliver up to 1 A DC current to the load depending on the
application conditions. The output voltage can be adjusted by a voltage divider supplying
either 3.3 V or 5 V. More detailed information on DC-DC conversion is introduced in
Chapter
The whole power supply has been realized on a single-side 35 µm PCB, whose total surface
amounts to 176 x 90 mm.
