A good PCB layout for optimal thermal performance would be to have a solid ground plane on the bottom layer, and to place thermal vias under the IC to dissipate heat. Additionally, keeping the input and output capacitors close to the IC can help reduce noise and improve efficiency.
The choice of input and output capacitors depends on the specific application requirements. For the MP23701GQEU-Z, a low-ESR ceramic capacitor with a value of 10uF to 22uF is recommended for the input capacitor, and a low-ESR ceramic or electrolytic capacitor with a value of 22uF to 47uF is recommended for the output capacitor.
The maximum ambient temperature for the MP23701GQEU-Z is 85°C, but it's recommended to derate the output current at higher temperatures to ensure reliable operation.
To ensure the converter meets the required EMC standards, it's recommended to follow proper PCB layout and design guidelines, use a shielded inductor, and add EMI filters or common-mode chokes as needed. Additionally, the converter should be tested and certified to the relevant EMC standards, such as EN55022 or CISPR22.
The recommended input voltage range for the MP23701GQEU-Z is 4.5V to 18V, but it can operate from 4V to 20V with reduced performance. It's recommended to operate the converter within the recommended input voltage range for optimal performance and reliability.
