Texas Instruments provides a recommended layout and placement guide in the TPS65012RGZR datasheet (Section 10.2) and in the application note 'TPS65012RGZR Layout Guidelines' (SLUU444). It's essential to follow these guidelines to ensure proper thermal performance, noise reduction, and overall device reliability.
The output capacitor selection depends on the output voltage, output current, and desired ripple voltage. Texas Instruments recommends using a low-ESR ceramic capacitor with a minimum capacitance of 10uF and a voltage rating of at least 1.5 times the output voltage. The application note 'TPS65012RGZR Output Capacitor Selection' (SLUU445) provides more detailed guidance.
The TPS65012RGZR has an absolute maximum input voltage rating of 6.5V. However, the recommended operating input voltage range is 3.5V to 5.5V. Exceeding the absolute maximum rating can damage the device.
The TPS65012RGZR has a junction temperature rating of 150°C. However, the device's performance and reliability may degrade at high temperatures. Texas Instruments recommends operating the device within the recommended temperature range of -40°C to 125°C for optimal performance and reliability.
Texas Instruments provides a troubleshooting guide in the TPS65012RGZR datasheet (Section 11) and in the application note 'TPS65012RGZR Troubleshooting Guide' (SLUU446). Common issues and their solutions are discussed, including output voltage instability, overheating, and input voltage undershoot.
