TPS62806YKAR Frequently Asked Questions (FAQs)
Texas Instruments provides a recommended PCB layout in the datasheet, but it's also recommended to follow general high-frequency layout guidelines, such as keeping the input and output capacitors close to the IC, using a solid ground plane, and minimizing trace lengths and widths.
The selection of input and output capacitors depends on the specific application requirements, such as voltage rating, capacitance value, and ESR. TI recommends using low-ESR ceramic capacitors with a voltage rating of at least 1.5 times the input voltage. A capacitance value of 4.7uF to 10uF is typically suitable for most applications.
The TPS62806YKAR is rated for operation up to 85°C ambient temperature, but it's recommended to derate the output current and voltage to ensure reliable operation at high temperatures. Consult the datasheet for thermal derating curves.
To ensure stability, follow the recommended PCB layout, use the recommended input and output capacitors, and ensure that the output voltage is within the specified range. Additionally, adding a small ceramic capacitor (e.g., 10nF) between the VIN and GND pins can help to prevent oscillations.
The recommended input voltage range for the TPS62806YKAR is 2.3V to 5.5V, but it can operate down to 2.0V with reduced performance. Operating outside of this range may affect the regulator's stability and output voltage accuracy.
