The TLV3702IDGK is a high-frequency device, so it's essential to follow good layout and placement practices to minimize noise and ensure optimal performance. TI recommends placing the device close to the power supply, using short traces, and avoiding vias under the device. Additionally, it's crucial to decouple the power supply with a 10uF capacitor and a 100nF capacitor in parallel.
The output capacitor selection depends on the desired output voltage ripple, output current, and stability requirements. A general rule of thumb is to use a capacitor with a value between 10uF to 22uF, with a voltage rating of at least 2x the output voltage. TI recommends using a low-ESR capacitor, such as a ceramic or film capacitor, to minimize output voltage ripple and ensure stability.
The TLV3702IDGK has an absolute maximum input voltage rating of 18V. However, it's recommended to operate the device within the recommended input voltage range of 4.5V to 15V to ensure optimal performance and reliability.
The TLV3702IDGK is rated for operation up to 125°C, but it's essential to consider the device's thermal characteristics and ensure proper thermal management. TI recommends using a heat sink or thermal pad to maintain a junction temperature below 125°C to ensure reliability and performance.
To ensure stability, it's crucial to follow the recommended layout and placement guidelines, use a suitable output capacitor, and decouple the power supply. Additionally, TI recommends adding a 10kΩ resistor in series with the output capacitor to prevent oscillation. If oscillation occurs, try adding a 10nF capacitor in parallel with the output capacitor.
