The recommended layout and placement for the TPS60403DBVTG4 involves placing the input and output capacitors close to the device, using short and wide traces for the power lines, and keeping the analog and digital grounds separate. A 4-layer PCB with a solid ground plane is recommended.
To ensure stability and prevent oscillations, it is recommended to use a minimum output capacitance of 10uF, keep the output capacitor ESR low, and use a low-ESR input capacitor. Additionally, the device should be operated within the recommended input voltage range and the output voltage should be set within the specified range.
The maximum ambient temperature range for the TPS60403DBVTG4 is -40°C to 85°C. However, the device can operate up to 125°C junction temperature, but the ambient temperature should be derated accordingly.
Yes, the TPS60403DBVTG4 is qualified for automotive and high-reliability applications. It meets the AEC-Q100 standard and is manufactured using a qualified process. However, additional testing and validation may be required for specific applications.
The power dissipation of the TPS60403DBVTG4 can be calculated using the formula: Pd = (Vin - Vout) x Iout. The junction temperature can be estimated using the thermal resistance (RθJA) and the power dissipation. The thermal resistance is specified in the datasheet.
