The recommended layout and placement for the TPS3836L30DBVT 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 to minimize the length of the traces between the device and the capacitors.
When choosing input and output capacitors for the TPS3836L30DBVT, consider the voltage rating, capacitance value, and equivalent series resistance (ESR). A general rule of thumb is to use a 10uF to 22uF ceramic capacitor for the input and a 10uF to 47uF ceramic capacitor for the output. The ESR of the capacitors should be less than 100mΩ.
The maximum ambient temperature range for the TPS3836L30DBVT is -40°C to 125°C. However, the device can operate up to 150°C with derating. It is essential to ensure that the device is operated within the recommended temperature range to ensure reliability and performance.
The output voltage of the TPS3836L30DBVT can be calculated using the following formula: Vout = 1.182V x (1 + R1/R2), where R1 and R2 are the resistors connected to the FB pin. The output voltage range is 0.9V to 5.5V.
The maximum input voltage for the TPS3836L30DBVT is 6.5V. Exceeding this voltage may damage the device. It is essential to ensure that the input voltage is within the recommended range to ensure reliability and performance.
