AC-DC module suitable for high voltage distributed power systems
TDK Corporation announces the introduction of the TDK-Lambda brand PF1500B-360 full brick power module. Rated at 1512W with an input of 170 to 265V or 1008W from 85 to 265V, the module delivers a non-isolated, regulated 360Vdc output with a 0.98 power factor. The PF1500B-360 is ideally suitable for high-voltage power systems using isolated DC-DC […]
A better way to handle dc/dc converter hold-up times
Converters with built-in holdup circuitry reduce the size and requirements for input capacitors. Dr. André Buffing, L. Dinkelmann, Traco Power DC/DC converters are generally designed to maintain their output despite brief interruptions of their input power. The duration of this output hold-up often is set by the value of an external capacitor connected across the […]

Key considerations when integrating high voltage DC-DC converters into critical applications
By Hafiz Khalid, Director of Product Marketing at XP Power Over the years, through observations in the field and conversations with design engineers, four challenges regularly present themselves when integrating high-voltage DC-DC power modules into critical, long-term applications. The most important criterium is to define the requirements of the power module correctly, then consider the […]
Low-cost 30-W dc-dc converter features 4:1 input range
30-W dc-dc converters in the new THL 30WI series come in a standard 1×1-in footprint. This next-generation product greatly improves the “cost/performance” ratio in the 30-W, 1×1-in industry standard product area. Combined with safety approvals to the latest IEC/EN/UL 62368-1 standards, the product is a candidate for mobile equipment, instrumentation, distributed power architectures and industrial […]
Zero-ohm jumpers handle up to 158 A
Zero-ohm jumpers are commonly used in a wide range of markets and end products. They make circuitry routing easier and simplify manufacturing. Jumper requirements for higher current levels frequently exceed the capability of general-purpose jumpers. The maximum current rating for thick film general-purpose jumpers is only 3 amps and high current thick film jumpers typically […]
1-W power modules integrate switching, control, transformer, input/output capacitors
Würth Elektronik has extended the product families of its MagI³C power modules with the MagI³C-FIMM Fixed Isolated MicroModule. It combines the features of an isolated power module with those of a MicroModule in an LGA-7 package and measures just 9 mm x 7 mm x 3.1 mm. The isolation capacitance between the primary and secondary windings […]
