STEVAL-ISA109V1

800 mA, 3 MHz, high efficiency dual mode buck-boost DC-DC converter based on the STBB2
  • active Active

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 VSELpin 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.
