Vicor recommends a 4-layer PCB with a solid ground plane on the bottom layer, and a thermal relief pattern on the top layer to ensure good thermal conductivity. A minimum of 2 oz copper thickness is recommended.
To ensure reliable start-up, Vicor recommends a soft-start circuit to limit the inrush current, and a minimum input capacitance of 10uF to ensure stable operation.
The maximum allowed input voltage ripple for the FARM1TN1 is 10% of the nominal input voltage. Exceeding this limit may affect the module's reliability and performance.
The FARM1TN1 is rated for operation up to 100°C, but derating is required above 85°C. Consult the datasheet for derating curves and thermal management guidelines.
Vicor recommends using an oscilloscope to monitor the input and output voltages, and checking for proper input voltage, output loading, and thermal conditions. Consult the datasheet and application notes for troubleshooting guidelines.
