Line filters are designed to replace discontinued Murata Components
Premier Magnetics announces the in-stock availability of its PMCU Series of common mode line filters designed for switching power supply applications. Offered in both standard winding (for higher efficiency) and sectional winding (for improved high-frequency performance), the PMCU line models provide a direct cross for over three dozen PLA10ANxxx and PLA10ASxxx EMIFIL series components recently […]
Power-supply noise, Part 2
Part 1 looked at the basics of noise, especially concerning power supplies. There are two noise sources which are not as obvious to many engineers as noise that results from the switching action of the power supply: differential mode noise and common-mode noise. These two noise modes have different causes and thus different solutions Q: […]
Power-supply noise, Part 1
“Noise”—perhaps nothing worries design engineers as much as the implications of this single five-letter word. There are good reasons for this worry. Noise is often unpredictable; may come from internal and somewhat controllable sources, or external impossible-to-control sources; it can affect performance accuracy and consistency; it can cause products to not meet their target design […]
Common-mode line filters for SMPS replace discontinued units
The PMCU Series of common mode line filters is designed for switching power supply applications. Offered in both standard winding (for higher efficiency) and sectional winding (for improved high-frequency performance), the updated PMCU offerings have been expanded to include a direct cross for over three dozen PLA10ANxxx and PLA10ASxxx EMIFIL series components recently discontinued by […]
Convection-cooled 250-W ac-dc power supplies handle limited airflow applications
Murata announces its new wide input range, single output PQC series of industrial/medical power supplies from Murata Power Solutions. Rated at 250 watts of output power in an industry-standard open frame 3 x 5 inch, 1U footprint, this high-efficiency design can deliver full power with free-air natural convection cooling up to 50°C. The PQC series […]
LED driver ICs offer 1W of power savings in LED boost circuit
Peregrine Semiconductor Corp., a Murata company, announces Arctic Sand’s new product family—the ARC3C family of LED driver ICs. The ARC3C product line targets the fast growing, ultra-high-definition (UHD) LCD displays market for notebook computers, Ultrabooks and 2-in-1 convertibles. The products deliver dramatic improvements in power conversion efficiency, while achieving the lowest “z” height profile and smallest […]
PoL DC-DC converters provide 90 A/162 W for FPGA and processor apps
Murata further expands its OKD series of Digital PoL DC-DC converters by launching the 90A/162W OKDx-T/90 series from Murata Power Solutions. This is the highest current-rated product in the OKD series, which already provides solutions from 6A to 60A. The OKDx-T/90 series is ideally suited for FPGA & processor applications. The module is specified to […]
Ultra-Thin Supercaps deliver 35 mF in a 20 x 20 x 0.4-mm package
Murata Americas today introduced its DMH series, a new lineup of supercapacitors with a thickness of 0.4mm, a μF order capacitance, low ESR, and the capability to output instantaneous power. The product line delivers a solution to devices with limited space that are challenged by power consumption issues since its slim package can be mounted in underutilized space. Further, the DMH can […]
Digitally controlled PoL operates in 4.5V to 14Vdc range in FPGA and processor applications
Murata introduces the OKDL-T/60-W12, a 60 Amp, 94.9% efficient addition to the Murata Power Solutions OKD family of digitally controlled point of load (PoL) DC-DC converters. The OKDL-T/60-W12 power module is ideally suited for FPGA and processor applications. The module is specified to operate over a Vin range of 4.5V to 14Vdc, and provides a […]
