STBB2 Dual Mode Buck-Boost DC-DC Converter Evaluation Board

The STM-STEVAL-ISA109V2-EVAL 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 O resistor and disconnecting R2. 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
