Description
The STEVAL-ISA109V1 is designed to aid in the
evaluation of the STBB2, a high efficiency buck-
boost DC-DC converter capable of providing
regulated output voltages in the range of 1.2 V to
5.5 V with an input voltage between 2.3 V and
5.5 V.

The board comes pre-mounted with the
adjustable version of the STBB2, with the output
voltage set to 3.3 V. For this version, the V
