TEA1721FT/N1,118 Frequently Asked Questions (FAQs)

A good PCB layout is crucial for the TEA1721FT/N1,118. NXP recommends a 4-layer PCB with a solid ground plane, and to keep the input and output tracks as short as possible. Additionally, it's essential to follow the layout guidelines provided in the application note AN11535.
The TEA1721FT/N1,118 can generate significant heat during operation. To ensure proper cooling, NXP recommends a heat sink with a thermal resistance of ≤ 10 K/W. Additionally, ensure good airflow around the device, and consider using a thermal interface material to improve heat transfer.
The recommended input capacitor value for the TEA1721FT/N1,118 is 10 μF to 22 μF, with an ESR of ≤ 100 mΩ. This ensures stable operation and minimizes voltage ripple.
The TEA1721FT/N1,118 output voltage can be configured using the FB (feedback) pin. Connect a resistive divider network between the output and the FB pin, and adjust the resistor values to achieve the desired output voltage.
The maximum input voltage for the TEA1721FT/N1,118 is 30 V. Exceeding this voltage can damage the device. Ensure the input voltage is within the recommended range of 8 V to 28 V for proper operation.
