A good thermal design should include a solid ground plane, thermal vias, and a heat sink. The datasheet provides some guidelines, but a more detailed application note from TI (SLUA623) provides additional guidance.
To ensure stability, it's essential to follow the recommended output capacitor selection and layout guidelines. TI provides a capacitor selection tool to help with this. Additionally, the datasheet provides guidance on output capacitor selection and layout considerations.
While the datasheet specifies an operating temperature range of -40°C to 125°C, the maximum ambient temperature for reliable operation depends on the specific application and thermal design. As a general guideline, TI recommends keeping the junction temperature below 125°C for reliable operation.
To handle high inrush current during startup, TI recommends using a soft-start circuit or a current-limited power supply. The datasheet provides some guidance on soft-start circuit design, and TI's application notes (e.g., SLUA623) provide additional information.
To minimize EMI and RFI, TI recommends following proper PCB layout and shielding techniques, such as using a shielded inductor, minimizing loop areas, and using a common-mode choke. TI's application notes (e.g., SLUA623) provide additional guidance on EMI and RFI mitigation.
