The recommended layout and placement for the TPS60403DBVRG4 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, it is recommended to use a minimum output capacitance of 10uF, and to place a 10nF capacitor in parallel with the output capacitor to filter out high-frequency noise. Additionally, the input voltage should be well-regulated and the device should be operated within its recommended operating conditions.
The maximum input voltage that the TPS60403DBVRG4 can handle is 5.5V. Exceeding this voltage may cause damage to the device.
The TPS60403DBVRG4 is rated for operation up to 85°C. However, the device's performance and reliability may degrade at higher temperatures. It is recommended to derate the device's output current and voltage at high temperatures.
The output voltage of the TPS60403DBVRG4 can be calculated using the formula: Vout = (R1/R2) * (Vref), where R1 and R2 are the resistors connected to the FB pin, and Vref is the internal reference voltage (1.2V).
