Evaluation Board based on the STBB2 - 800 mA, 3 MHz, Adjustable Output High Efficiency Dual-mode Buck-boost DC-DC Converter
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 VSELpin must be connected to VIN. The board can also demonstrate the performance of the fixed version of the STBB2, by replacing R1with a 0 Ω resistor and disconnecting R2.
The STBB2 is a fixed frequency, high efficiency, buck-boost DC-DC converter which provides output voltages from 1.2 V to 4.5 V starting from input voltage from 2.4 V to 5.5 V. The device can operate with input voltages higher than, equal to, or lower than the output voltage making the product suitable for single Li-Ion, multi-cell alkaline or NiMH applications where the output voltage is within the battery voltage range.
Applications: Memory card supply, Cellular phones
