This user guide supports the evaluation kit for the FAN48610. It should be used in
conjunction with the FAN48610 datasheet as well as Fairchild’s application notes and
technical support team. Please visit Fairchild’s website at www.fairchildsemi.com.
1. Description
The FAN48610 evaluation board is a compact circuit including Fairchild’s FAN48610
synchronous boost regulator with Pass-Through Mode in a 9-bump Wafer-Level ChipScale Package (WLCSP). Small input/output capacitors and a 470 nH inductor ensure
smooth output regulation.
The board also features an on-board active load circuit and footprints to accommodate
additional input/output capacitors. The evaluation board provides probe access points to
all key circuit nodes so that electrical characteristics can be measured.
