4.1.7 TP8 (5V), J10 (3.3V), TP7 (SYS_PWR)

Use the TP8, and J10 test points to measure the output voltage of the onboard DC/DC converters. These DC/DC converters produce the required voltage rails for full functionality of the EVM including power delivery, powering internal and external circuits, and so forth. These test points allow the user to verify the system supplies on the TPS65994EVM. LDO_1V5 is internally generated for internal circuitry. Use P3V3 to supply VIN_3V3 which then supplies LDO_3V3. Also, use LDO_3V3 as a low power output for external flash memory. In bus-powered conditions, or self-powered conditions, LDO_3V3 is active. TP7 test point is provided to verify input voltage of barrel jack connector.
