The TLV3701CD is a high-frequency device, so it's essential to follow good layout practices to minimize noise and ensure proper operation. TI recommends placing the device close to the power supply, using short traces, and avoiding vias under the device. A solid ground plane and decoupling capacitors are also crucial.
The output capacitor selection depends on the desired output voltage ripple, output current, and stability. A general rule of thumb is to use a capacitor with a value between 1uF to 10uF, with a voltage rating at least 1.5 times the output voltage. X5R or X7R ceramic capacitors are good options. TI also provides a capacitor selection guide in the datasheet.
The TLV3701CD has an absolute maximum input voltage rating of 6V. However, the recommended input voltage range is 2.7V to 5.5V. Exceeding the absolute maximum rating can damage the device.
The TLV3701CD is rated for operation up to 125°C. However, the device's performance and reliability may degrade at high temperatures. TI recommends derating the output current and voltage at high temperatures to ensure reliable operation.
To troubleshoot issues with the TLV3701CD, start by checking the input voltage, output voltage, and output current. Verify that the device is properly decoupled and that the layout follows good practices. Use an oscilloscope to check for oscillations or ringing on the output. TI also provides a troubleshooting guide in the datasheet and application notes.
