DMOS microstepping driver features translator & overcurrent protection
Allegro MicroSystems Europe has announced a integrated bipolar stepper motor driver IC with built-in translator for easy operation. Allegro’s A5984 is designed to operate bipolar stepper motors from full-step up to 1/32 step modes that are selectable by MSx logic inputs.
The latest chemistries found for liquid batteries
Liquid metal batteries, invented by MIT professor Donald Sadoway and his students a decade ago, are a promising candidate for making renewable energy more practical. The batteries, which can store large amounts of energy and thus even out the ups and downs of power production and power use, are in the process of being commercialised by a Cambridge-based startup company, Ambri.
BF medical power supplies offer leading power density
Powerbox has announced a series of power supplies for BF (Body Floating) medical applications. Complying with the latest EMI coexistence standard IEC 60601-1-2: 2014 (4th edition) and specifically designed with patient and operator safety in mind, the OBS01 series delivers an output power of 1100W (1250W peak), which is market leading power density – OBS01 is available in seven different voltages from 24 to 48V with an efficiency up to...
Cooling management features on AC-DC power supplies
High input voltage power supplies manufactured by EFORE are now available at Luso Electronics. The ROAL branded DDP400 mid-range ultra-efficient AC-DC power supplies offer typical efficiencies of 94% and efficiency load profiles that exceed 80 PLUS Platinum requirements. The open-frame, u-chassis and punched cover versions of the DDP400 are suitable for challenging system designs where a low profile is desired and a low power dissipation is nece...
Advanced modules meet ultracapacitor applications
The complete family of iMOD X-Series modules for ultracapacitor applications from Ioxus is now available from distributor Richardson Electronics. The iMOD X-Series modules have a wide voltage range, can deliver and absorb a high current, operate from-40⁰C to +85⁰C and have a long life cycle.
Power inductors are optimised for high frequency applications
At the Applied Power Electronics Conference (APEC 2016) in California, USA, Coilcraft has introduced a series of low-loss power inductors. The XEL40xx series is offered with lower inductance values that have been fully optimised for high frequency applications. They also offer extremely low DCR down to 2.5mΩ and ultra-low AC losses, resulting in the highest efficiency across a range of frequencies from 2 to over 5MHz.
Low-profile 5A power module targets telecomms & SSDs
Designed specifically for height-constrained telecomms, industrial and SSD applications, an integrated switching power module has been unveiled by Microchip. The MIC45404 integrates inductors and passive components in a 10x6x2mm thermally-enhanced package, which saves space, simplifies board design and eliminates concern over passive components that may introduce unexpected EMI.
Immediately operate & evaluate a complete power system
Allowing power system designers to immediately begin operating and evaluating a complete power system solution featuring the industry’s thinnest, highest performance, highest density power components, Vicor announces its AC to PoL Development Kit (ACPoL DKit).
Digital hybrid PWM controllers are PMBus compatible
Offering PoL conversions for FPGAs, DSPs, ASICs, processors and general purpose system rails, Intersil has launched two digital hybrid DC/DC controllers. The ISL68200 with integrated MOSFET drivers and ISL68201 with PWM output simplify power supply designs for data centre routers, servers and storage, as well as wireless infrastructure equipment.
Buck converter reduces system noise & saves space
Texas Instruments has announced a 2.2MHz, dual-channel synchronous buck converter which reduces EMI and high-frequency noise in high-voltage DC/DC step-down applications such as automotive infotainment and high-end cluster power-supply systems. The LM5140-Q1 includes dual outputs with phase interleaving and is offered in wettable flank packaging that enables post-solder visual inspection to speed manufacturing.
