The recommended layout and placement for the TPS3801L30DCKR involves placing the device close to the power source, using a solid ground plane, and keeping the input and output capacitors close to the device. Additionally, it is recommended to use a low-ESR capacitor for the input capacitor and a low-ESL capacitor for the output capacitor.
The choice of input and output capacitors for the TPS3801L30DCKR depends on the specific application requirements. In general, a low-ESR capacitor with a value of 1-10uF is recommended for the input capacitor, and a low-ESL capacitor with a value of 1-22uF is recommended for the output capacitor. The capacitor values and types should be chosen based on the specific requirements of the application, such as the input voltage, output voltage, and output current.
The maximum input voltage that the TPS3801L30DCKR can handle is 18V. Exceeding this voltage may cause damage to the device.
To ensure the TPS3801L30DCKR is stable and does not oscillate, it is recommended to follow the layout and placement guidelines, use a low-ESR input capacitor, and ensure that the output capacitor is properly sized for the specific application. Additionally, it is recommended to add a small ceramic capacitor (e.g. 10nF) between the VIN and GND pins to help stabilize the device.
The typical startup time for the TPS3801L30DCKR is around 1-2ms. However, this time may vary depending on the specific application and the input voltage.
