How to use

Install the MPM-15-3.3 on the device PCB using the through-hole pins, ensuring proper solder joints and mechanical support. Connect the AC input per the device wiring diagram and route the DC 3.3 V output to the target circuit, observing polarity and load limits. Verify isolation clearances and follow the device’s layout guidelines to maintain creepage and clearance distances for medical safety.

Recommendations

Use the power supply within its specified input range (90–264 V AC) and rated output current (3.5 A). Provide adequate ventilation and avoid placing heat-sensitive components directly above the unit. For medical applications, ensure system-level compliance testing and maintain required isolation and grounding practices.
