Texas Instruments provides a recommended PCB layout in the datasheet, but it's essential to follow good PCB design practices, such as keeping the power and ground planes separate, using a solid ground plane, and minimizing trace lengths and widths. Additionally, ensure that the input and output capacitors are placed close to the device.
The choice of input and output capacitors depends on the specific application and operating conditions. Generally, use low-ESR capacitors with a high ripple current rating. For the input capacitor, a 10uF to 22uF ceramic capacitor is recommended, while for the output capacitor, a 10uF to 47uF ceramic capacitor is suitable. Consult the datasheet and application notes for more information.
The SM72480SD-105/NOPB is rated for operation up to 125°C ambient temperature. However, it's essential to consider the thermal design and ensure that the device is properly cooled to maintain a safe operating temperature. Consult the thermal design guidelines in the datasheet and application notes.
To ensure EMC compliance, follow good PCB design practices, such as using a solid ground plane, minimizing trace lengths and widths, and using shielding and filtering components as necessary. Additionally, consult the datasheet and application notes for specific guidance on EMC compliance.
The recommended input voltage range for the SM72480SD-105/NOPB is 4.5V to 18V. Operating outside this range may affect the device's performance and reliability. Consult the datasheet for more information on input voltage range and tolerance.
