NPS4053 load switch evaluation board

The NPS4053 evaluation board is a specialized PCB designed for the Nexperia load switch family. The PCB features test points for GND, VIN, VOUT, FLG and EN, which allow for convenient connection of oscilloscope probes. Designed with user-friendliness in mind, it streamlines the testing and analysis of the load switch's dynamic characteristics, such as RON and smooth turn-on measurements.

Key features and benefits

> Input voltage can be supplied via the test points, VIN can range from 2.5 V to 5.5 V.
> Decoupling capacitors are connected to VIN at the input of the evaluation board and close to the load switch IC. The same holds for the output.
> VIN_Sense and VOUT_Sense are used when accurate measurements of the input or output are required. Make RON measurements using these Kelvin sense connections when measuring the voltage drop from VIN to VOUT.
