Power adapter MEAN WELL MDD01M-05 1 W Input 10.8-13.2 V Output 5 V

The MEAN WELL MDD01M-05 is a compact DC‑DC medical converter designed for PCB mounting. It accepts a wide DC input range of 10.8–13.2 V and provides dual isolated outputs of ±5 V at ±0.1 A, delivering up to 1 W of total output power. The module is built in a SIP through‑hole package and meets 2×MOPP isolation requirements, which makes it suitable for low‑power medical and industrial applications where board‑level isolation and small footprint are required. The component is RoHS‑compliant, reflecting the manufacturer’s adherence to environmental standards.

Advantages

The converter combines a small SIP through‑hole form factor with dual isolated outputs, enabling straightforward PCB integration without additional enclosure space. Its input range covers typical 12 V systems, and the ±5 V bipolar outputs simplify designs that require both positive and negative rails. The 2×MOPP isolation enhances patient and operator safety in medical designs, while the low 1 W power rating reduces thermal management needs in densely populated boards.

Suitable for

• Low‑power medical devices and diagnostic modules requiring isolation
• Portable and battery‑powered equipment with a nominal 12 V supply
• Instrumentation and sensor interface circuits needing ±5 V rails
• PCB‑mounted power solutions in compact industrial electronics

Key specifications

• Input voltage range: 10.8–13.2 V DC
• Output configuration: dual isolated outputs, ±5 V
• Output current: ±0.1 A per rail
• Total output power: 1 W
• Isolation: 2×MOPP suitable for medical applications
• Package type: SIP through‑hole for PCB mounting
• Compliance: RoHS

How to use

Mount the SIP through‑hole converter directly onto the PCB following the manufacturer’s recommended footprint and spacing to maintain isolation creepage and clearance. Connect the DC input within the specified 10.8–13.2 V range and route the isolated outputs to the circuitry that requires ±5 V rails. Observe polarity and grounding practices appropriate for medical converters: keep primary and secondary circuits separated and use proper creepage and clearance on the PCB to preserve 2×MOPP performance. Verify output voltages under expected load conditions before final assembly.

Recommendations

For reliable operation, ensure adequate spacing between the converter and other high‑voltage or heat‑dissipating components, and confirm ambient temperature limits in your design. When used in medical equipment, follow applicable medical safety standards and perform necessary isolation and leakage testing during system validation.
