NXP provides a recommended PCB layout guidelines in the application note AN11562, which includes thermal design considerations and layout recommendations for optimal performance.
The input capacitor value depends on the input voltage, output voltage, and output current. NXP recommends using the capacitor selection tool available on their website or consulting the application note AN11562 for guidance on selecting the correct input capacitor value.
According to the datasheet, the maximum allowed voltage on the enable pin is 6V. However, it's recommended to keep the enable pin voltage within the range of 0V to VCC (typically 5V) to ensure proper operation.
The PDTC143T,315 is rated for operation up to 150°C. However, it's essential to consider the thermal design and layout to ensure the device operates within its specified temperature range. NXP provides guidance on thermal management in the application note AN11562.
NXP provides a troubleshooting guide in the application note AN11562, which covers issues such as output voltage regulation, efficiency, and thermal performance. Additionally, NXP's support team can be contacted for further assistance.
