PoL converter carries integrated SVID for Intel systems
Infineon Technologies AG introduces the newest member of its integrated point-of-load product family, the IR38164 DC-DC POL converter. Infineon’s IR38x6x family offers either full SVID compatibility or 3-bit PVID flexibility. This makes it easy to design and support Intel CPU and chipset POL rails in Intel systems. Some products support PMBus functionality for POL rails […]
DC-DC converter provides self-contained power for USB PD and QC 4.0
The ACT4751 from Active Semiconductor is a 4.5 to 40V input, high efficiency synchronous step-down DC-DC converter that supplies two additional output channels to support USB PD controllers like the Cypress CCG3PA and active USB-C cable VCONN power requirements. The ACT4751 is fully integrated and controls the two integrated 50mOhm MOSFETs to achieve the highest […]
Quarter-brick dc-dc converter provides 1.3 kW with 97.3% typical efficiency
Flex Power Modules announces the launch of the BMR490, a non-isolated digital IBC (Intermediate Bus Converter) DC-DC converter with an output power of 1300W in the quarter-brick form factor. The new converter combines very high power density with excellent thermal performance in a price-sensitive design, making it ideal for demanding applications such as data centers. […]
100 V, 1 A DC/DC buck converter extends battery life
Texas Instruments introduced a wide-input-voltage (VIN) synchronous DC/DC buck converter with the industry’s best combination of light load efficiency, ease of design and overall power solution cost. The 100-V, 1-A LM5164 step-down voltage converter shrinks board space in rugged battery-powered industrial and automotive power supplies. Used in conjunction with TI’s WEBENCH Power Designer, this new […]
1×1-in railway dc/dc converters tackle demanding environments
The RP12-AR series dc/dc converters are designed for railway rolling stock applications, but they are also suitable for non-railway high-voltage battery applications. Their 5:1 input voltage range of 36-160 Vdc (185 Vdc for 1 sec) allows for all-in-one solutions for 48-V, 72-V, 96-V and 110-Vdc railway systems. They have a built-in class A filter network […]
Powering graphics processors from a 48-V bus
New converter topologies and power transistors promise to reduce the size and boost the efficiency of supplies that will run next-generation AI platforms. Alex Lidow | Efficient Power Conversion Artificial Intelligence (AI), gaming, cloud computing, and autonomous vehicles all employ the latest generation of graphics processors (GPUs) in lieu of CPUs. The reasoning is that […]

Key factors in power supply selection
It pays to understand a few important electrical parameters that can dictate the kind of applications specific power supplies can handle. Florian Haas | Traco Power Group A few basic factors go into the selection of low-voltage dc/dc and ac/dc power supplies for OEM use. At the risk of stating the obvious, the key objective […]
Switchers say bye-bye to EMI
Electromagnetic interference can emanate from high di/dt loops found in some switch-mode supply topologies. New controllers overcome these difficulties by integrating key components inside the chip package. Tony Armstrong | Power by Linear, Analog Devices Inc. It goes without saying that PCB layout sets functional, electromagnetic interference (EMI) and thermal behavior of every power supply […]
