FPF230X Evaluation Board
The FPF230X evaluation board has components and circuitry to
demonstrate FPF2300/2/3 load switch functions and features,
accommodating both the MLP 3x3mm and SO8 packages. The
state of the each channel can be configured using J1 and J2
jumpers. In addition, both channels can be controlled by ONA
and ONB test pints. Thermal performance of the board is
improved using techniques in the layout recommendations
section. R3 and R4 resistors are used on the board to sink a
light load current when switches are activated.
