Bivar recommends a thermal pad on the bottom of the package, connected to a large copper area on the PCB to dissipate heat efficiently. A minimum of 2oz copper thickness is recommended.
Bivar recommends securing the MPC3AD with a suitable adhesive or mechanical fastening to prevent movement and vibration-induced damage. Additionally, ensure that the PCB is properly secured to the system's chassis or enclosure.
Although the datasheet specifies a maximum input voltage of 5.5V, Bivar recommends limiting the input voltage to 5V to ensure reliable operation and prevent damage to the internal ESD protection diodes.
While the MPC3AD is rated for operation up to 85°C, Bivar recommends derating the current output by 1.5mA for every 10°C above 70°C to ensure reliable operation and prevent overheating.
Check the input voltage, output load, and PCB layout for any issues. Ensure that the output pins are not overloaded, and the input voltage is within the recommended range. Use an oscilloscope to verify the output waveform and check for any signs of overheating or electrical noise.
