Reference Designs and Analog ICsTarget Hybrid and Electric Vehicles
Texas Instruments (TI) has introduced fully tested reference designs for battery management and traction inverter systems, along with new analog circuits with advanced monitoring and protection features to help reduce carbon dioxide emissions and enable hybrid electric vehicles and electric vehicles (HEV/EVs) to drive farther and longer.
Scalable across six- to 96-series cell supervision circuits, TI's new battery management system (BMS) reference design (shown) features the BQ79606A-Q1 precision battery monitor and balancer. Engineers can get their automotive designs to market quickly using the reference design, which implements the battery monitor in a daisy chain configuration to create a highly accurate and reliable system design for three- to 378-series, 12-V up to 1.5 kV lithium-ion battery packs.

Rad-Hard PWM Controller and GaN FET Drive Feature Plastic Package
Renesas Electronics has announced what it claims are the space industry's first plastic-packaged, radiation-tolerant PWM controller and Gallium Nitride (GaN) FET driver for DC/DC power supplies in small satellites (smallsats) and launch vehicles. The ISL71043M single-ended current mode PWM controller and ISL71040M low-side GaN FET driver are well suited for isolated flyback and half-bridge power stages, and motor control driver circuits in satellite buses and payloads. Private "new space" companies have begun launching smallsats to form large constellations operating in multiple low Earth orbit (LEO) planes. Smallsat mega-constellations provide global broadband Internet links, as well as high-resolution Earth observation imaging for sea, air and land asset tracking. The ISL71043M PWM controller provides fast signal propagation and output switching in a small 4 mm x 5 mm SOIC plastic package, reducing PCB area up to 3x compared to competitive ceramic packages.

Isolated DC-DC Converters Meet PoE Requirements
Murata Manufacturing has expanded its lineup of isolated DC-DC converters for Power over Ethernet (PoE). The additions to the lineup consist of the following two isolation type DC-DC converter products intended for Powered Devices (PD) and also the following isolation type DC-DC converter product intended for Power Sourcing Equipment (PSE). The MYBSP0055AABFT is 5 V output /5.1 A product for PDs. The MYBSP0122BABFT is a 12 V output /2.1 A product also for PDs. And the MYBSS054R6EBF is a 54 V output/0.6 A device for PSEs.
These products are suitable for biometric authentication devices which are required mainly to occupy minimal space and possess low noise characteristics. They're also suited for powering IoT gateways and camera modules. They also contribute to miniaturization of conventional wireless access points, IP telephones and routers. These products are already being mass produced and Murata can provide samples upon request.

30 W DC-DC Converters Blend High Power Density, Compact Size
MINMAX Technology has announced the MJWI30 series range of 30 W isolated DC-DC power modules with ultra-wide input ranges in the compact package measuring only 1.0" à 1.0" à 0.4". The devices offer a very high-power density up to 75 W-per-cubic-inch. This level of integration offers system designers the opportunity to reduce overall PCB layout area or add more features into existing PCB profiles. The MJWI30 family of DC-DC converters consists of 14 models offering 9-36 VDC or 18-75 VDC input ranges with single output models ranging 3.3-24 VDC and dual output models ±12 V or ±15 V delivering 30 W of output power.
All models feature: I/O Isolation of 1,500 VDC, high efficiency up to 90%, operating ambient temperature range of -40°C to +80°C , faster start-up, fully regulated outputs with high precision, no minimum load requirement, very low no-load power consumption, shielded metal package and under-voltage/overload/short-circuit protection.

Space Qualified DC-DC Converters Leverage GaN Technology
VPT has released its SGRB Series of space qualified DC-DC converters. Using advanced GaN technology, the SGRB is capable of very high efficiency, up to 95%, as well as radiation tolerance. A fixed-frequency reduced voltage switching topology results in very low input and output noise, making it suitable for use in telecommunication systems.
Specifically designed for applications facing the harsh radiation environments of space, the SGRB Series has been characterized to Total Ionizing Dose (TID) of 100 krad(Si), including Enhanced Low Dose Rate Sensitivity (ELDRS), and Single Event Effects (SEE) performance to 85 MeV/mg/cm-squared. The SGRB Series features an integrated EMI filter, 100 V input and 28 V, 400 W output, and is rated for full power operation from -35°C to 85°C. VPT is reviewing specific customer requests for custom orders of the SGRB Series.
