The RBB10-2.0-EVM-1 evaluation board generates a regulated output voltage with a current up to 4A from an external DC supply which can be higher, lower or the same as the set output voltage.
The output voltage is preset to 3.3V or 5V but can be adjusted between 1.0V and 5.5V using on-board resistors. All of the functions of the RBB10-2.0 regulator such as the different operating modes, output trim, enable, and the sense input can be easily evaluated using the break out connectors.
Typical applications that can be evaluated include:
USB voltage converter/regenerator: 3.3V or 5V output from a 3.3V (+60%/-30%) or from a 5V (+10%/-50%) supply. A stable output voltage can be regenerated even if the input voltage is outside of the USB voltage specification.
Battery stabiliser: the output can be set to deliver a stable 5V or 3.3V from a nominal 3V, 3.7V or 4.2V Lithium Ion or 3V/4.5V alkaline battery pack. In standby, the board consumes only 5µA.
Supercapacitor booster: the output can be set to deliver a stable 5V or 3.3V from a single supercapacitor (2.3V – 2.7V) or from two supercapacitors wired in series (2.3V – 5.4V).
Low voltage regulator with sense: 1V, 1.2V, 1.8V or 2.5V output with up to 4A current
