| | | DC-DC Controllers Integrate Active EMI Filter |
| Texas Instruments (TI) has introduced a new family of synchronous DC-DC buck controllers that enable engineers to shrink the size of the power-supply solution and lower its electromagnetic interference (EMI). Featuring an integrated active EMI filter (AEF) and dual-random spread-spectrum (DRSS) technology, the LM25149-Q1 and LM25149 enable engineers to cut the area of the external EMI filter in half, says TI. |

| | | 1200V MOSFET Modules Meet High Power Density Needs |
| Infineon Technologies has upgraded its EasyDUAL CoolSiC MOSFET modules with a new aluminum nitride (AIN) ceramic. The devices come in half-bridge configuration with an on-state resistance of 11mΩ in an EasyDUAL 1B package and 6mΩ in an EasyDUAL 2B package (shown). With high-performance ceramic, the 1200 V devices are suitable for high-power density applications. |

| | | 60A DC-DC Converter Eyes 5G, IT and IIoT Gear |
| ABB Power Conversion has announced its new MicroDLynx II DC-DC converters that help meet the power needs of demanding, data-hungry applications, providing highly accurate voltage regulation in a compact, 232-mm-squared footprint—with a power density of 167A/in-squared. Pushing the boundaries of advanced IT and networking devices requires improvements in component density and functionality, says ABB. This equates to designing board-level power modules in ever-shrinking, high density packages. |

| | | Datasheet: Power/Battery Management ICs |
| Battery-powered systems—including power tools, electric vehicles wearable electronics, IoT edge devices and more—depend on the proper managing of battery power. To keep pace, all sorts of innovations have been happening in power management ICs (PMICs), battery monitoring ICs and more. This Datasheet section updates readers on this technology and provides a sampling of representative ICs. |

| | | 3kW AC-DC Power Supplies Deliver 150-800VDC |
| XP Power has Introduced the HDL3000-HV series of single-phase input 3kW AC-DC power supplies with output voltages from 150V to 400VDC, with up to 800VDC realized by connecting units in series. All models feature output voltage and current adjustment ranging from 0 to 105% using analog (via voltage or resistance) or digital (I2C, RS485 and RS232) interfaces enabling the user to optimize and tailor the power solution to the application. |
