4 Power Supplies
Digital Interface
The TSC2046EVM is designed to easily interface with multiple control platforms. Samtec part numbers
SSW-110-22-F-D-VS-K and TSM-110-01-T-DV-P provide a convenient 10-pin, dual-row, header/socket
combination at J2. This header/socket provides access to the digital control and serial data pins of the
TSC. Consult Samtec at www.samtec.com or call 1-800-SAMTEC-9 for a variety of mating connector
options.

J3 provides connection to the common power bus for the TSC2046EVM. Power is supplied on the pins
listed in Table 3 .

When power is supplied to J3, JMP5 allows for one of four different DC voltages to be applied to the
digital sections of the TSC. See the schematic and printed circuit board silkscreen for details.
The TSC2046EVM-PDK motherboard (the USB-MODEVM Interface Board) supplies power to J3 of the
TSC2046EVM. Power for the motherboard is supplied either through its USB connection or on terminal
blocks on the board.
