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
