Description
The STEVAL-ISA063V1 demonstration board
represents a typical buck-boost DC-DC converter
application, intended to demonstrate the function
and performance of the STBB1XX device. The
STBB1XX is a fixed frequency, high efficiency Dc-
DC converter capable of providing output voltages
ranging from 1.2 V to 5.5 V, and input voltages
from 2.0 V to 5.5 V.

The STBB1XX device can operate with input
voltages higher than, equal to, or lower than the
output voltage, making the product suitable for
single Li-ion, multi-cell alkaline or NiMH battery-
powered applications where the output voltage is
within the battery voltage range. The integrated
