Power supplies deliver 1300W from a 108-264VAC input

Power supplies deliver 1300W from a 108-264VAC input
Delivering 1300W from a 108-264VAC universal input, the D1U3CS series of front-end AC/DC power supplies has been released by Murata. The power supplies are hot pluggable and have no minimum load requirement. For fault-tolerant and N+1 redundant applications, the devices incorporate low-loss integral ORing FETs on the main 12V output.

Buck-boost converter extends usable life of Li-ion batteries

Buck-boost converter extends usable life of Li-ion batteries
Designed to prolong battery life in single-cell Li-ion battery applications where the output voltage is within the battery voltage range, the XC9306 converter has been released by Torex Semiconductor. When discharged, a Li-ion battery's operating voltage declines to the point that it can no longer power it's load. The synchronous buck-boost converter boosts the output voltage of the battery, extending it’s usable life.

SPICE model delivers SiC MOSFET benefits

SPICE model delivers SiC MOSFET benefits
A new SPICE model introduced by Cree increases the design-in support for the C2M Series SiC MOSFET power devices and demonstrates the benefits of Cree SiC MOSFETs—including the new C2M0025120D device, which recently shattered the on-resistance barrier by delivering 1200V of blocking voltage with an on-resistance of only 25mOhms—in circuit simulations.

BLDC motor driver reduces audible noise by up to 75%

BLDC motor driver reduces audible noise by up to 75%
Claimed to be the industry’s first 24V, sinusoidal, sensorless, BLDC motor driver, the DRV10983 has been announced by Texas Instruments. The motor driver uses 180°, sinusoidal, sensorless technology to reduce audible noise by up to 75% compared to competing solutions for applications such as cooling fans, ceiling fans, blowers and small appliances.
