Description
This evaluation board is based on L6728, a single-phase step-down controller with integrated high-current drivers that provides complete control logic and protection to realize in a simple way general DC-DC converters by using a
compact VFQFPN-10 package.
STEVAL-ISA038V1
The board realizes in a two-layer PCB a stepdown DC-DC converter and shows the operation of the device in a general-purpose low-current application.
The input voltage can range from 5 V to 12 V buses and the output voltage is fixed at 1.25 V.
The application can deliver an output current in excess of 5 A.
The switching frequency is 300 KHz.
