evaluation board

Data Brief

General description

The L6902D evaluation board integrates the step-

down switching regulator with adjustable current

limit L6902D as well as the external components

required for a typical application.

The input voltage of the application 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

1.235V up to 10V, which is the rated voltage of the

output capacitor.

Evaluation board

A current limit of 1A is programmed by the 100mΩ

sense resistor R

sense

The inductor saturation current and the forward

current of the schottky rectifier fit the current limit

setting.
