Texas Instruments provides a recommended PCB layout in the datasheet, but it's also recommended to follow general high-frequency layout guidelines, such as keeping the input and output traces short and separate, using a solid ground plane, and placing decoupling capacitors close to the device.
The selection of input and output capacitors depends on the specific application requirements, such as the input voltage range, output voltage, and output current. A general guideline is to use low-ESR capacitors with a value of 10uF to 22uF for the input capacitor and 10uF to 47uF for the output capacitor. It's also recommended to follow the capacitor selection guidelines in the datasheet.
The TPS2829DBVRG4 has an operating junction temperature range of -40°C to 125°C, but the maximum ambient temperature range depends on the specific application and the thermal design of the system. A general guideline is to keep the ambient temperature below 85°C to ensure reliable operation.
To ensure stability, it's recommended to follow the compensation guidelines in the datasheet, which include selecting the correct compensation components and placing them close to the device. Additionally, it's recommended to use a low-ESR output capacitor and to avoid using a large output capacitor with a high ESL.
The TPS2829DBVRG4 has a maximum output current capability of 2A, but the actual output current capability depends on the input voltage, output voltage, and ambient temperature. It's recommended to derate the output current capability based on the specific application requirements and thermal design.
