Product information

Description

The MEAN WELL MDD01L-05 is a compact PCB-mount DC-DC converter designed for medical and industrial electronics requiring isolated dual outputs. It accepts an input voltage from 4.5 to 5.5 V DC and provides dual ±5 V outputs with up to ±0.1 A per rail, delivering 1 W total output power in a SIP through-hole package with reinforced isolation (2×MOPP). The module is RoHS compliant and suited for integration into space-constrained designs.

Advantages

This module combines a small footprint and SIP through-hole mounting for easy PCB assembly with medical-grade isolation (two MOPP) to protect patients and equipment. It produces stable ±5 V rails from a low-voltage input and offers predictable performance at up to ±0.1 A per output. The unit’s conformity to RoHS simplifies material compliance for end products.

Suitable for

Medical devices and instruments requiring isolated dual rails
Portable electronics and battery-powered systems with 5 V supplies
Signal conditioning, sensors, and measurement circuits needing ±5 V
PCB-mounted power solutions in compact assemblies

When it may not be suitable

This converter provides limited output current (±0.1 A per rail) and 1 W total power; it is not suitable for applications that require higher load currents or significant power margins. It is intended for PCB mounting in a SIP through-hole package, so projects needing surface-mount modules or chassis-mounted power supplies should consider other form factors.

Key specifications

Input voltage: 4.5–5.5 V DC
Output configuration: dual outputs, ±5 V
Output current: up to ±0.1 A per output
Total output power: 1 W
Package: SIP through-hole PCB mount
Isolation: two MOPP (medical-grade reinforced isolation)
RoHS compliance

How to use

Mount the SIP converter on the PCB using the through-hole pins and follow the manufacturer’s recommended PCB layout for isolation creepage and clearance. Supply the module with a stable 4.5–5.5 V DC input and verify output polarity before connecting sensitive circuitry. Observe thermal and load limits: keep output currents within ±0.1 A per rail and provide adequate ventilation or copper area on the PCB for heat dissipation.

What to consider before purchase

Required output current and total power—ensure ±0.1 A per rail and 1 W meet your needs
Form factor—SIP through-hole mounting compatibility with your PCB
Isolation level—two MOPP for medical applications if patient protection is required
Input voltage compatibility with your power source (4.5–5.5 V DC)

Usage recommendations

For reliable operation, design PCB layout to maintain required creepage/clearance for medical isolation, keep output loading within specified limits, and validate thermal performance in the final enclosure. Use the module where isolated ±5 V rails at low current are sufficient and monitor regulation under your specific load conditions.
