TPS65313-EVM User’s Guide
The TPS65313-Q1 device is a power management integrated circuit (PMIC) for safety-relevant automotive applications. This device integrates a wide-input voltage off-battery buck regulator (BUCK1), a low-voltage buck regulator (BUCK2), and a 5-V boost converter (BOOST). The TPS65313-Q1 device integrates protection features such as independent voltage monitors, overtemperature protection, watchdog function, and built-in analog and digital diagnostic tests. The features of the device target safety-relevant applications with system-safety requirements up to ASIL-C level.
This user's guide provides instructions to power up and evaluate the TPS65313-Q1 device using the TPS65313-EVM evaluation module (EVM) and software user interface (TPS65313 GUI).

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.
Table 1. Input and Output Voltages and Load-Current Requirements
| Regulator Name | Input Voltage | Output Voltage(2) | Maximum Load Current |
|---|---|---|---|
| BUCK1 | 6 V to 18 V (VBAT)(1) | 3.3 V or 3.6 V (VBUCK1) | 3.1 A |
| BUCK2 | 3.3 V or 3.6 V (VBUCK1) | 1.2 V or 1.25 V or 1.8 V or 2.3 V (VBUCK2) | 2 A |
| BOOST | 3.3 V or 3.6 V (VBUCK1) | 5 V (VBOOST) | 0.6 A |
