NXP provides a recommended PCB layout in the application note AN11561, which includes guidelines for thermal vias, copper pours, and component placement to minimize thermal resistance and ensure reliable operation.
The input capacitor selection depends on the input voltage, current, and ripple requirements. NXP recommends using a low-ESR capacitor with a minimum capacitance of 10uF and a voltage rating of at least 1.5 times the input voltage. Refer to the application note AN11561 for more detailed guidance.
The maximum allowed voltage drop across the PDTC143EK,115 is 0.5V. Exceeding this voltage drop may affect the device's reliability and performance. Ensure that the input voltage and output voltage are within the recommended operating range.
To ensure EMC, follow the guidelines in the application note AN11561, which includes recommendations for PCB layout, component selection, and shielding. Additionally, consider using a common-mode choke and a shielded inductor to minimize electromagnetic interference.
The recommended operating temperature range for the PDTC143EK,115 is -40°C to 125°C. However, the device can operate up to 150°C with derating. Refer to the datasheet for more information on temperature derating and thermal management.
