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 […]
Galvanically isolated transformers work with IGBT, SiC-MOSFET gate drivers
Power Integrations announced a range of galvanically isolated transformers that provide the correct voltage and power for the company’s SCALE-iDriver family of gate drivers. The combination delivers a simple, robust and cost-efficient DC-DC converter solution that does not require additional voltage regulation, reducing system cost and development time. The SIT12xxI transformer and SCALE-iDriver ICs are […]
What you need to know about buzzers – reviewing the basic types and technologies
Bruce Rose, Principal Applications Engineer, CUI Inc A buzzer can provide a cost-effective yet intuitive aspect to the user interface of a wide variety of products, such as a home appliance, security panel, door-entry system or computer peripheral. Usually the choice is between either a magnetic or piezoelectric type. It should be an easy decision, […]
GaN power transistors cover 3.5-A to 11-A range
The GS-065 low current (3.5 A to 11 A) transistor line, developed for sub-1k W power applications, is targeted for consumer level power supply products such as ac adapters for gaming and workstation laptops, TV power, LED lighting, wireless power systems, and appliance motor drives. This new transistor line leverages GaN Systems’ technology leadership in […]
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.

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 […]
