The recommended layout and placement for the TPS3808G01DBVRG4 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. A 4-layer PCB with a solid ground plane is recommended. Refer to the Texas Instruments application note 'TPS3808 Layout and Placement Guidelines' for more information.
The choice of input and output capacitors for the TPS3808G01DBVRG4 depends on the specific application requirements. A general guideline is to use low-ESR capacitors with a capacitance value of 10uF to 22uF for the input and output. The capacitor voltage rating should be at least 1.5 times the maximum input voltage. Refer to the datasheet and application notes for more information.
The maximum operating temperature range for the TPS3808G01DBVRG4 is -40°C to 125°C. However, the device can operate up to 150°C for a short duration during power-up and power-down. Refer to the datasheet for more information.
The TPS3808G01DBVRG4 has a built-in overvoltage protection feature that can be enabled by connecting the OV pin to a voltage divider network. The OV pin threshold is 1.2V, and the device will shut down if the input voltage exceeds the threshold. Refer to the datasheet and application notes for more information.
The maximum input voltage for the TPS3808G01DBVRG4 is 6.5V. However, the device can withstand up to 7V for a short duration during power-up and power-down. Refer to the datasheet for more information.
