Texas Instruments provides a recommended PCB layout in the datasheet, but it's also important to follow general best practices for switching regulator layouts, such as keeping the input and output capacitors close to the IC, using a solid ground plane, and minimizing trace lengths and widths.
To ensure stability, make sure to follow the recommended component values and PCB layout, and also consider the output capacitor's ESR (Equivalent Series Resistance) and ESL (Equivalent Series Inductance) when selecting the output capacitor. Additionally, adding a small ceramic capacitor (e.g. 10nF) between the VOUT and GND pins can help to improve stability.
The maximum input voltage rating for the LM2738XSD/NOPB is 42V, but it's recommended to operate the device within the specified input voltage range (7V to 36V) for optimal performance and reliability.
The LM2738XSD/NOPB has a maximum operating junction temperature of 150°C, but it's recommended to operate the device within the specified temperature range (-40°C to 125°C) for optimal performance and reliability. Additionally, consider the thermal derating of the device and the PCB when operating in high-temperature environments.
The output voltage of the LM2738XSD/NOPB can be calculated using the formula: VOUT = (R1 / R2) * 0.8V, where R1 and R2 are the resistors connected to the FB pin. The output voltage range is adjustable from 0.8V to 15V.
