1 TPS65313-EVM Top View With Basic External Connections
Figure 1 shows the top-view diagram of the EVM along with basic connections. The BUCK1 input supply
and an optional USB cable (for SPI communication) are the only two external connections required for this
EVM. The BUCK2 regulator and BOOST converter are supplied through onboard jumper connections from
the BUCK1 output and therefore no external supply voltage is required for the BUCK2 regulator and
BOOST converter.

2 TPS65313-EVM Input, Output Voltages, and Load Current Requirements
Table 1 lists the input and output voltage for each regulator and their maximum load-current requirements.
(1)
To supply the BUCK2 regulator and BOOST converter, use the onboard VBUCK1 supply (jumper J5, VSUP).
(2)
The input voltage range on VIN, AVIN, and VIN_SAFE pins at which full device functionality and performance is assured.
Operation outside this input voltage range is possible and for detailed recommended operating conditions, refer to
TPS65313-Q1
Wide-VIN Power-Management IC for Automotive Applications datasheet.
