A good PCB layout for the LMR23610AQDDAQ1 should include a solid ground plane, wide power traces, and a thermal relief pattern under the device to facilitate heat dissipation. TI provides a recommended PCB layout in the datasheet and application notes.
To ensure stability, follow the recommended component values and PCB layout guidelines in the datasheet. Additionally, use a low-ESR output capacitor, and consider adding a small ceramic capacitor in parallel with the output capacitor to filter out high-frequency noise.
The absolute maximum input voltage rating for the LMR23610AQDDAQ1 is 42V. However, it's recommended to operate the device within the specified input voltage range (3.5V to 36V) for optimal performance and reliability.
The LMR23610AQDDAQ1 is rated for operation up to 125°C. However, the device's performance and reliability may degrade at high temperatures. Consider using thermal management techniques, such as heat sinks or thermal interfaces, to maintain a safe operating temperature.
Choose an output capacitor with a low equivalent series resistance (ESR) and a high ripple current rating. A ceramic or polymer capacitor with a value between 10uF to 22uF is a good starting point. Consider the output voltage, output current, and switching frequency when selecting the output capacitor.
