Description:The MAU300 series is a range of 2W DC-DC converters in a small SIP Package featuring an I/O-isolation of 1000VDC. An excellent efficiency allows an operating temperature range of –40℃ to +85℃.
Minmax recommends a 4-layer PCB with a solid ground plane and thermal vias to dissipate heat. A minimum of 2oz copper thickness is recommended for the top and bottom layers. Additionally, a thermal pad on the bottom of the device should be connected to a heat sink or a thermal interface material.
Minmax recommends using a reflow soldering process with a peak temperature of 260°C (500°F) and a dwell time of 20-30 seconds. Ensure the PCB is clean and dry before soldering, and use a solder paste with a melting point of 217°C (423°F) or higher. Avoid using excessive solder or flux, and inspect the joints under a microscope to ensure proper wetting and filleting.
The maximum allowed voltage drop across the input and output pins is 1.5V. Exceeding this voltage drop may affect the device's performance, efficiency, and reliability. Ensure that the input and output capacitors are properly selected and placed to minimize voltage drops.
Minmax recommends using a multimeter to measure the input and output voltages, currents, and temperatures. Check for proper PCB layout, thermal management, and component selection. Use an oscilloscope to analyze the output voltage ripple and noise. Consult the datasheet and application notes for troubleshooting guidelines and contact Minmax's technical support for further assistance.
The MAU321 is designed to meet CISPR 22 Class B and EN 55022 Class B EMI standards. Ensure proper PCB layout, grounding, and shielding to minimize EMI. Use a common-mode choke and EMI filters on the input and output lines. Consult the datasheet and application notes for EMI/EMC guidelines and consult with a qualified EMI/EMC engineer to ensure compliance with regulatory standards.
