Ideal Power introduces its New Medical DC/DC Converter: The 4168DW10-M Series

Medical electronics often need more from a DC/DC converter than the correct input and output voltage. Electrical isolation, leakage current, PCB space, input variation and EMC requirements can all affect component choice.

The new 4168DW10-M medical DC/DC converter, manufactured by Yuan Dean, brings these features together within a compact 10W DIL package.

The series offers reinforced insulation, 5,000V AC RMS input-to-output isolation, leakage current below 2µA and wide 4:1 input ranges. Single and dual output models are available, with efficiency reaching up to 85%.

Key benefits of the 4168DW10-M

The 4168DW10-M combines several features that can benefit medical, industrial and ITE applications:

5,000V AC RMS input-to-output isolation supports circuits that need electrical separation.

Reinforced insulation is rated for a 250V AC working voltage.

Leakage current below 2µA helps keep the converter’s contribution to system leakage low.

Wide 4:1 input ranges support changing DC supply voltages.

Single and dual outputs give designers more choice across different circuit requirements.

Efficiency up to 85% helps reduce conversion losses and heat.

Compact 31.6 × 20.1 × 10mm DIL package helps save PCB space.

Medical EMC documentation gives engineers useful information during the design stage.

Operation from −40°C to +82°C with derating supports a broad range of temperature conditions.

Remote on/off, output adjustment and short-circuit protection give greater control over system integration.

Reinforced isolation supports electrical separation

Electrical separation can play an important role in medical electronic designs. The 4168DW10-M can withstand 5,000V AC RMS between input and output for 60 seconds. It uses reinforced insulation rated for a 250V AC working voltage.

This can benefit equipment such as a bedside patient monitor, where communications or signal-processing circuits may need to remain electrically separated from other parts of the system.

Leakage current below 2µA helps control system leakage

Low leakage current helps reduce how much the converter contributes to the total leakage current of the finished equipment.

The 4168DW10-M has a leakage current below 2µA, giving designers a low figure to work with during development.

This can be useful in portable diagnostic equipment where isolated signal-processing or communications circuits need tight control over leakage current.

A 4:1 input range supports changing supply conditions

A wider input range gives designers more flexibility where the available DC voltage changes during use. The 4168DW10-M offers 4:1 input ranges covering either 9–36V DC or 18–75V DC.

A portable ultrasound scanner, for example, may run from an internal battery before connecting to an external DC source or charging system. The wider input range helps the converter handle these changing voltage conditions.

Single-output models cover 3.3V, 5V, 12V, 15V and 24V DC. Dual-output versions include ±5V, ±12V and ±15V DC.

This gives designers more options when matching the converter to different circuit requirements.

Up to 85% efficiency helps reduce heat

The 4168DW10-M reaches efficiency levels of up to 85%, depending on the model and operating conditions. This can benefit portable and enclosed medical electronics where several components share limited internal space. Efficient conversion can help reduce heat inside compact electronic equipment.

Compact DIL dimensions save PCB space

The 4168DW10-M measures 31.6 × 20.1 × 10mm and weighs 13.5g. Its through-hole DIL format allows direct PCB installation. This compact footprint can benefit patient monitoring, diagnostic and portable equipment where available board space is limited.

The case uses UL94V-0 plastic material, giving designers useful flammability information for the finished product.

Medical EMC made easier to review

Having relevant EMC information available early can make component selection much easier. The 4168DW10-M lists EN 55011:2009+A1:2010 Class A and EN 60601-1-2:2015. This can be useful for equipment such as infusion pumps, which may operate close to patient monitors.

The IEC 60601-1-2 standard covers EMC requirements for medical electrical equipment. This gives engineers useful EMC information during the design stage, before the finished device goes through its own testing.

Wide temperature performance supports varied environments

The 4168DW10-M operates from −40°C to +82°C with derating and has a storage range from −55°C to +125°C. This can suit portable medical equipment that moves between clinical, transport and storage environments.

The converter has a maximum case temperature of 95°C, with every unit undergoing 100% burn-in testing. It also comes with a three-year warranty.

Added control over integration and fault response

The 4168DW10-M includes several useful control and protection features.

Remote on/off lets the host system control the converter without removing the main input supply. External output adjustment of up to ±10% gives designers more flexibility when setting the required voltage.

Hiccup-mode short-circuit protection helps protect the converter during a fault and automatically attempts recovery once the short circuit clears. These features can make the converter easier to integrate into the finished system.

A new option for medical DC/DC conversion

The new 4168DW10-M combines reinforced isolation, low leakage current, wide 4:1 input ranges and a compact DIL package within a 10W converter.

Its single and dual output options, efficiency up to 85%, medical EMC documentation and broad temperature range add further flexibility across medical, industrial and ITE applications.

For designs where electrical separation, PCB space and changing input conditions all matter, the 4168DW10-M gives engineers a practical new option to consider.
