■ Nominal output current (I
■ Switching frequency: 300 kHz
Description
The STEVAL-ISA037V1 evaluation board is a
step-down DC-DC converter based on the L6728,
a single-phase step-down controller with
integrated high-current drivers. The L6728 device,
packaged in the compact VFQFPN 10, provides
complete control logic and protection for simple
implementation of general DC-DC converters.
This four-layer PCB evaluation board shows the
operation of the device in a general-purpose
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 of up to
30 A. The switching frequency is 300 kHz.
