The recommended layout and placement for the TPS3803-01DCKRG4 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 'TPS3803 Layout and Placement Guidelines' for more information.
The choice of input and output capacitors for the TPS3803-01DCKRG4 depends on the specific application requirements. A general guideline is to use low-ESR capacitors with a minimum capacitance of 10uF for the input and output. X5R or X7R ceramic capacitors are recommended. The capacitor selection should also consider the voltage rating, temperature range, and ripple current requirements.
The maximum ambient temperature range for the TPS3803-01DCKRG4 is -40°C to 125°C. However, the device can operate up to 150°C with derating. Refer to the datasheet for more information on thermal derating.
The TPS3803-01DCKRG4 has a built-in overvoltage protection (OVP) feature that can be enabled by connecting the OVP pin to a voltage source. The OVP threshold can be set by selecting the appropriate resistor values. Refer to the datasheet for more information on implementing OVP with the TPS3803-01DCKRG4.
The minimum input voltage required for the TPS3803-01DCKRG4 to operate is 2.7V. However, the device can operate down to 2.5V with reduced performance. Refer to the datasheet for more information on the input voltage range.
