TI provides a recommended PCB layout in the datasheet (section 10.2) and in the TPS65130RGETG4 Evaluation Module documentation. It's essential to follow these guidelines to minimize noise, ensure proper thermal dissipation, and optimize performance.
The output capacitor selection depends on the output voltage, output current, and desired ripple voltage. TI provides a capacitor selection guide in the datasheet (section 7.3.1) and in the TPS65130RGETG4 Capacitor Selection Tool. It's recommended to use a low-ESR capacitor with a minimum capacitance of 10 μF.
The TPS65130RGETG4 has an absolute maximum input voltage rating of 18 V. However, the recommended operating input voltage range is 4.5 V to 15 V. Applying voltages above 15 V may reduce the device's reliability and lifespan.
The TPS65130RGETG4 has built-in OVP and UVP features. OVP is set to 12.6 V (typical) and UVP is set to 4.3 V (typical). These thresholds can be adjusted using external resistors (R_OVP and R_UVP) connected to the OVP and UVP pins, respectively.
The thermal derating curve is provided in the datasheet (section 10.1). The device's output current capability decreases as the junction temperature increases. It's essential to ensure proper thermal design and heat sinking to maintain the device's performance and reliability.
