The TLV3702IDGKR is a high-frequency device, so it's essential to follow good PCB layout practices to minimize noise and ensure proper operation. Place the device close to the power supply, use short traces, and avoid vias under the device. Also, ensure that the input and output traces are well-separated to minimize crosstalk.
To ensure proper operation, it's recommended to power up the TLV3702IDGKR after the power supply has stabilized. When powering down, ensure that the input voltage is removed before the output voltage. A soft-start circuit can be used to control the power-up sequence and prevent inrush currents.
The maximum allowed capacitance on the output of the TLV3702IDGKR is 10nF. Exceeding this value can cause instability and affect the device's performance. If a larger capacitance is required, consider using an external resistor in series with the capacitor to limit the current.
The TLV3702IDGKR is rated for operation up to 125°C. However, the device's performance and reliability may degrade at high temperatures. Ensure that the device is properly heatsinked and that the ambient temperature is within the recommended operating range.
Oscillations or instability issues can be caused by poor PCB layout, inadequate decoupling, or incorrect component selection. Check the PCB layout for noise coupling, ensure that the input and output capacitors are properly selected, and verify that the device is properly decoupled. If the issue persists, consult the Texas Instruments support resources or contact a local representative for assistance.
