Description
The STEVAL-ISA109V1 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 pre-mounted with the
adjustable version of the STBB2, 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
