A recommended PCB layout is to use a solid ground plane, keep the input and output traces separate, and use a common mode choke to reduce EMI. A 4-layer PCB with a dedicated power plane and a solid ground plane is recommended.
To ensure reliability, operate the device within the recommended temperature range, use a heat sink if necessary, and ensure good airflow around the device. Also, follow the recommended derating curves for temperature and output current.
The CDRH127/LDNP-561MC has built-in EMI filtering, but additional filtering may be required depending on the application. A common mode choke and X-capacitors can be used to reduce EMI. Follow the recommended layout and component selection guidelines for optimal EMI performance.
Yes, the CDRH127/LDNP-561MC can be used in parallel to increase output current. However, it is essential to ensure that the devices are properly synchronized and that the output currents are balanced to prevent uneven current sharing.
A low-ESR ceramic capacitor with a value of 10-22uF is recommended for the input of the CDRH127/LDNP-561MC. The capacitor should be placed as close to the device as possible to minimize noise and ensure stable operation.
