Figure 4-2. ADCIN1 and ADCIN2 Configuration Schematic
4.1.4 J2: Barrel Jack Power Connector
The barrel jack power connector accepts a 19-V to 20-V DC supply. A standard notebook adapter (or similar
adapter) provides the required power. This input provides the PP_EXT power rail 19-V to 20-V.
Figure 4-3. Barrel Jack (J2) Schematic
4.1.5 USB Type-C™ Connector (J3_PA, J3_PB)
The TPS65994 EVM has two full feature USB Type-C receptacles (port A/B) and routes VBUS, SSTX and SSRX
pairs, SBU1 and SBU2 pairs, and D+ and D– signals. The TPS65994 device can be used in self-powered and
bus-powered configurations for added flexibility. When self-powered, the EVM can provide up to 15 W (5 V, at 3
A) of power per port via the internal PP5V power path. The EVM is also capable of sinking 100 W (20 V, at 5 A)
of power via the external PP_EXT power path. The internal power path is used for sourcing power and the
external power path is used for sinking power.
