Description
The STEVAL-ISA109V2 is designed to aid in the
evaluation of the STBB2, a high efficiency buckboost 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 with the adjustable version of
the STBB2 pre-mounted, with the output voltage
set to 3.3 V. For this version, the VSEL pin must be
connected to VIN.
The board can also demonstrate the performance
of the fixed version of the STBB2, by replacing R1
with a 0 Ω resistor and disconnecting R2.

Features
• Input voltage: from 2.3 V to 5.5 V
• Output voltage: 3.3 V
