DC motor driver overcomes space constraint challenges
A single-chip IC for driving single-coil reversible DC fans and motors has been introduced by Diodes. Designated the ZXBM5210, the IC reduces component counts and circuit footprints in medium and low power applications, and is available in a choice of SO8 and thermally enhanced SO8 exposed pad packages.
Configurable power supply assemblies handle rugged conditions
Luso Electronics Distribution, the sole UK and Ireland representative for SynQor’s power supplies and related components, has announced availability of MultiQor Plate - a new line of DC-DC configurable assembly power supplies designed for the extreme environmental and demanding electrical conditions of military and aerospace applications.
Board design simplified with cloud-based Wizard
Taking the guesswork out of board design, GE's cloud-based Power Module Wizard provides board designers with an intuitive tool to help them easily select the optimal DC/DC modules for their power board. The Power Module Wizard allows board designers to select the right power module on the first try, thereby improving design productivity, reducing risks and virtually eliminating the need to rework their designs.
Buck regulator offers switching frequencies to 4 MHz
Offering high programmable switching frequencies to 4 MHz, the Siliconix SiP12108 signals an expansion of the exisiting microBUCK family of integrated synchronous buck regulators from Vishay. Providing designers with a complete high-current solution in only 180 mm², the regulator features high- and low-side power MOSFETs in a space-saving 3 mm by 3 mm QFN-16 package.
Regulators' synchronous rectification delivers 96% efficiency
Featuring synchronous rectification delivering efficiency as high as 96%, the LT8610A and LT8610AB step-down switching regulators from Linear are suitable for automotive and industrial applications. Quiescent current is kept under 2.5µA in no-load standby conditions, due to the incorporated Burst Mode operation, whilst the input voltage ranges from 3.4V to 42V.
Secure electrical energy supply for new hospital
Eaton announce that it has recently installed a Medium Voltage system for a new hospital in The Netherlands. The largest non-academic hospital in The Netherlands at 108,000m2, Isala Klinieken uses Eaton’s MV switchgear alongside a Power System Automation (PSA) solution to ensure a secure electrical energy supply for the complex.
Solderable top side improves power cycling capabilities
Designed to improve the power cycling capabilities of power modules, top side solderable metallization has been introduced by IXYS on 200A and 300A, 650V Trench XPTTM IGBT silicon dies. Solderable top side replaces standard bond wire connections by using the standard soldering process, thereby improving power cycling capability and increasing the surge current capabilities of the dies.
Dual TrenchFET MOSFETs suit vehicle telematics
Believed to be one of the industry's first automotive-qualified dual MOSFETs in an asymmetric package, the SQJ940EP and SQJ942EP dual n-channel TrenchFET power MOSFETs have been announced by Vishay. Operating over a wide temperature range from -55 to +175°C, the MOSFETs provide the ruggedness and reliability required for in-vehicle applications.
DC/DC converter balances high voltage battery stacks
Featuring isolated balancing design and system telemetry, Linear’s LT8584 monolithic flyback DC/DC converter is designed to actively balance high voltage stacks of batteries. The active balancing offered with the DC/DC converters redistributes the charge from the stronger cells to charge the weaker cells during discharge. This enables the weaker cells to continue to supply the load, extracting 96% of the entire stack capacity where passive ...
Qi-certified wireless power receiver IC for smartphones
Toshiba Electronics Europe have announced the introduction of a new wireless power receiver IC, the TC7761WBG. Compliant with Qi Standard Low Power Specifications version1.1, the TC7761WBG wireless IC will be used in wireless power supply applications, such as smartphones and mobile accessories.
