STEVAL-ISA109V2
800 mA, 3 MHz, adjustable output 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-ISA109V2 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 with the adjustable version of
the STBB2 pre-mounted, with the output voltage
set to 3.3 V. For this version, the V_SEL pin must be
connected to V_IN.
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.
