STEVAL-ISA109V1

800 mA, 3 MHz, high efficiency dual mode buck-boost DC-DC

converter based on the STBB2

Data brief

Features

■ Input voltage: from 2.3 V to 5.5 V

■ Output voltage: 3.3 V

■ Output current: 800 mA

■ Operating frequency: 3 MHz

■ RoHS compliant

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 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.
