The DC/DC power converter market is accelerating fast. With rising demand for energy-efficient power solutions in electric vehicles, datacom, telecom, and high-performance computing, you need reliable technology to keep up with the pace. That’s where the NDQ Series, supplied by PPM Power, delivers high-efficiency, digitally controlled performance.

 

Unlock Next-Level Efficiency

The NDQ Series of non-isolated DC/DC converters delivers up to 1600 W with a 12.25 V output and achieves up to 98% peak efficiency. This means you gain measurable savings in power and cooling costs, and greater overall system reliability.

Each model shares the same quarter-brick footprint, mechanical design and electrical interface , giving you the flexibility to scale power ratings without redesigning your system layout.

Engineered for Demanding Environments

The NDQ Series thrives in environments where uptime and efficiency matter most. Designed to perform from –40°C to +85°C with forced-air cooling, these converters deliver stable operation and high performance even under extreme or variable loads.

NDQ900 offers up to 900 W at 96.7% efficiency. Perfect for 48 V to 12 V down conversion in high-performance computing. Optional PMBus® interface provides digital monitoring and control for smarter system management.

NDQ1300 delivers up to 1300 W with a flat 98% efficiency curve, ensuring minimal heat and simpler thermal design. The integrated baseplate supports heatsinks or liquid cooling for optimal performance. It’s fully qualified to IEC 62368 for global compliance.

NDQ1600 powers up to 1600 W with 97.7% peak efficiency, supporting remote sense and current share operation. Ideal for scalable high-density power systems in AI servers, robotics and advanced storage.

Each NDQ module is digitally controlled for precision, performance and monitoring flexibility. You gain real-time visibility and control of power parameters, enhancing reliability and system intelligence.

The Smart Choice for the Future

As industries evolve towards higher energy efficiency and smarter systems, the NDQ Series gives you the edge. Its compact design, wide-range efficiency and digital intelligence help you reduce operational costs, increase system uptime and accelerate product innovation.

You can now reduce board space while maximising efficiency with the HQA Series isolated DC-DC converters, available from PPM Power in 85 W and 120 W versions. These compact quarter bricks give you reliable performance in the toughest environments.

The HQA Series maximises your power density while saving valuable board space. You benefit from efficiency levels up to 92%, reducing wasted energy and improving system reliability.

The rugged, encapsulated design and efficient magnetic feedback loop deliver stable output even at high altitude or in harsh environments. The converters ensure performance at environmental extremes, working reliably at operating temperatures from as low as -55°C ambient and up to 115°C (baseplate temperature).

Pairing the HQA converters with FQA or FQB MIL-COTS EMC filters helps you meet demanding MIL-STD compliance requirements. That means faster qualification and less design risk.

You can choose input ranges of 9 V to 40 V or 18 V to 40 V, with 50 V for one second. Remote on/off control, up to 3000 Vdc input-to-output isolation, and enhanced screening options further increase flexibility for your COTS, communications and industrial equipment designs.

The product serves a wide range of applications, from MIL-COTS uses like trucks, airplanes, portable equipment, RF amplifiers, detection systems, and battery chargers, to harsh industrial environments such as high-temperature security systems and outdoor installations, delivering reliable performance in both commercial and extreme conditions.

New EMC filters have been added to PPM Power’s range of DC/DC Power supplies, designed to meet demanding military, aerospace, and industrial standards with confidence. As a result, these modules provide reliable protection, simpler compliance, and lower system noise.

FQA Filters

FQA filters reduce both differential and common mode conducted emissions from dc-dc switching converters, helping you meet MIL-STD-461G with less effort. Furthermore, they protect against input spikes in line with MIL-STD-1275D and RTCA/DO-160G. Rated at ±40Vdc and 20A, with a typical DC resistance of only 12mΩ, FQA filters minimise power losses. Cooling is flexible too: they can be used with a standard quarter brick heat sink or mounted to a cold plate.

FQB Filters

FQB filters extend protection with strong noise attenuation combined with active suppression circuitry to block input surges and transients. This enables straightforward compliance to MIL-STD-461, MIL-STD-1275, RTCA/DO-160 and MIL-STD-704. Built in against reverse input, under / over-voltage and over-current keeps your system safe. With ultra-low no-load consumption (as little as 1.5mA with remote off) and low resistance, you not only extend battery life, you also reduce energy loss, making your system more reliable and efficient.

RGF Filters

RGF filters provide powerful EMI filtering for high current systems. Available in 20 and 40 A versions, these modules provide outstanding differential mode filtering, simplifying compliance to CISPR and other standards. Their robust, encapsulated design fits easily into conduction or convection-cooled systems. With broad frequency attenuation, transient resistance up to 100V, and operation from -40°C to +120°C, RGF filters ensure consistent performance even in the toughest industrial, defence, or communications environments.

Select standard or enhanced screening for extended temperature operation down to -55°C and additional burn-in testing, giving you extra confidence in your system’s reliability.

With these EMC filters, you gain faster design cycles, lower risk, improved efficiency, and protection that keeps your systems performing at their best.
