STEVAL-ISA155V1, Evaluation Board integrates the L6902D step-down switching regulator with adjustable current limit, together with the external components required for a typical application. The input voltage of the board can range from 8V up to 25V due to the rated voltage of the input capacitor and the Schottky rectifier repetitive peak reverse voltage (both 25V). The external resistor divider (R1 and R2) sets the output voltage of the application board to 3.3V. A different output voltage can be regulated from 1.235 V up to 10V according to the rated voltage of the output capacitor
