Vishay Introduces Industry-Advanced Small 6A, 20A and 25A Buck Regulator Modules to Increase POL Converter Power Density

 


【Lansheng Technology Information】September 6, 2023 - Vishay Technology announced the launch of new 6A, 20A and 25A microBRICK® synchronous buck regulators - SiC967, SiC931 and SiC951, used to improve the point of load (POL) Converter power density and efficiency. The Vishay Siliconix SiC967, SiC931 and SiC951 are housed in a 10.6x6.5x3mm package with a smaller footprint and height than similar devices on the market, with an input voltage range of 4.5 to 60V.


The regulator modules released today are 69 percent smaller than other solutions, and each module integrates two high-performance MOSFETs, an inductor, a controller, and requires minimal external components for configuration and loop compensation. Device miniaturization significantly increases power density, while high integration reduces design complexity and speeds time to market. The regulator's controller consumes little static power and has a peak efficiency of up to 97%. MicroBRICK regulators are ideal for data center, communications infrastructure, and industrial applications, efficiently powering FPGA, ASIC, and SoC core supplies, helping to reduce energy consumption.


The regulator is highly configurable with a wide input voltage range and an adjustable output voltage down to 0.3V. In addition, the SiC931 has four programmable switching frequencies of 600kHz, 1MHz, 1.5MHz and 2MHz, and the adjustable switching frequencies of the SiC967 and SiC951 are 100kHz to 2MHz and 300kHz to 1.5MHz, respectively. All three devices can adjust the current limit, the SiC931 can also adjust the soft start, and the PMBus 1.3 compliant SiC951 supports three operating modes: continuous, tracking and simultaneous.


The voltage regulator modules provide general-purpose solutions for a wide range of applications, including server POL converters, cloud computing, high-performance computing, desktops, industrial automation, motor drives and power tools, monitoring systems, consumer electronics, and 5G communication equipment. For these applications, the SiC951 and SiC967 offer three operating modes: forced continuous operation, ultrasonic and energy saving. SiC931 provides forced continuous operation and power-saving mode. In power-saving mode, when the inductor current crosses zero, the control circuit turns off the low-side MOSFET and deploys diode emulation mode. Switching frequency drops proportionally with load conditions. There is no lower limit to the switching frequency to achieve the highest possible efficiencies at light loads.

What are the Benefits of Power Optimizers?

Image
  Power optimizer for solar panels is a DC/DC converter that is connected to each solar panel in the PV system, turning them into smart modules. By constantly monitoring the maximum production capacity of each individual solar module, optimizers can increase your PV plant energy production – potentially increasing revenue and shortening system payback time. Simply put, the main benefit of power optimizer is that it maximizes the performance of each panel individually. What are the benefits of power optimizers and why are they needed? When installing solar panels, the panels are connected into groups or arrays. In the case of roof-mounted and in-roof panels, there are usually 12-20 solar panels in one group. If the productivity of one of these panels decreases (shadows from trees and clouds, dust, bird droppings, failures of PV components and other factors), then the productivity of the whole group decreases. Defective or shaded panels may produce 15 to 25 percent less solar energy ...

What is a Power Conditioner?

Image
  Looking to protect your sensitive and expensive electronics? Surge protection is a great start, but power conditioners also offer valuable protection for components in entertainment and sound systems, as well as home office devices. What does a power conditioner do that a surge protector can’t? Surge protectors are a great defense against damaging voltage spikes. However more than surges and spikes can effect certain sensitive electronic devices. Radio frequency interference (RFI), electro-magnetic interference (EMI) and voltage fluctuations can also effect sound, entertainment, and office devices, causing a reduction in sound and picture quality. How does it work? Power conditioners act as a buffer between the outlet and your system, smoothing out voltage fluctuations as well as radio and electromagnetic interference that can effect system performance. Initially used in industrial, research and laboratory applications, not long after the introduction of home computer systems, th...
