Texas Instruments recommends a compact layout with the input and output capacitors placed close to the device, and the feedback resistors placed close to the output pin. A star-ground configuration is also recommended to minimize noise and ensure stability.
To ensure stability, make sure to follow the recommended layout and placement guidelines, use a sufficient output capacitor (at least 1uF), and ensure that the feedback resistors are properly sized. Additionally, avoid using long traces or wires for the feedback loop, and consider adding a small capacitor (e.g. 10nF) in parallel with the feedback resistors to improve stability.
The TLV9022DGKR has an absolute maximum input voltage rating of 6V. However, the recommended maximum input voltage is 5.5V to ensure reliable operation and prevent damage to the device.
The TLV9022DGKR is rated for operation up to 125°C, but its performance and reliability may degrade at high temperatures. It's recommended to derate the output current and voltage at high temperatures, and to ensure that the device is properly heatsinked to prevent overheating.
The output voltage ripple of the TLV9022DGKR can be calculated using the formula: ΔVout = (Iout * ESL) / (Cout * fsw), where Iout is the output current, ESL is the equivalent series inductance of the output capacitor, Cout is the output capacitance, and fsw is the switching frequency. A lower output voltage ripple can be achieved by using a larger output capacitor, reducing the output current, or increasing the switching frequency.
