STEVAL-ISA038V1
Single-phase 5 A step-down converter based on PWM controller with power-good L6728

This evaluation board is based on the L6728, a single-phase step-down controller with integrated high-current drivers that provides complete control logic and protection to implement in a simple way general DC-DC converters by using a compact VFQFPN-10 package.

The board provides a step-down DC-DC converter on a two-layer PCB 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 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.
