STEVAL-ISA026V1
Step-down DC-DC converter at 3.3 Vout/20 A at switching frequency 250 kHz based on L6732

This 4-layer PCB demo board implements a step-down DC-DC converter and shows the operation of the L6732 device in a general-purpose application. The input voltage can range from 4.5 V to 14 V and the output voltage is 3.3 V. The module can deliver an output current in excess of 20 A. The switching frequency is set at 250 kHz (controller free-running FSW), but it can be set to 500 kHz.
