Texas Instruments provides a recommended PCB layout in the datasheet, but it's also recommended to follow general high-frequency PCB design guidelines, such as using a solid ground plane, minimizing trace lengths, and using bypass capacitors.
To ensure stability, it's essential to follow the recommended compensation network and component values, and to ensure that the output capacitor has a low equivalent series resistance (ESR). Additionally, the input capacitor should be placed close to the IC and have a low ESR.
The maximum input voltage rating for the LM2750SDX-5.0/NOPB is 15V, but it's recommended to operate the device within the specified input voltage range (5.5V to 12V) to ensure reliable operation and to prevent damage to the device.
The LM2750SDX-5.0/NOPB is rated for operation up to 125°C, but it's essential to ensure that the device is properly derated for high-temperature operation and that the PCB and surrounding components can withstand the elevated temperatures.
The output voltage ripple and noise can be calculated using the equations provided in the datasheet, taking into account the output capacitor value, ESR, and the switching frequency. Additionally, the output voltage ripple can be measured using an oscilloscope.
