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 voltage of 36V to ensure proper start-up. Additionally, a 10uF ceramic capacitor should be placed close to the VIN pin to filter out noise.
The maximum output capacitance recommended by Vicor is 220uF. Exceeding this value may cause instability or oscillations in the converter.
Vicor recommends using a TVS (Transient Voltage Suppressor) diode or a voltage clamp circuit to protect the converter from input voltage transients. A 47uF input capacitor can also help to filter out noise and transients.
The maximum ambient temperature for reliable operation of the V48C24C150BG is 85°C. Operating the converter above this temperature may reduce its reliability and lifespan.
