Ethernet adapter technology powers HPE computer modules
Provider of semiconductor products that enable secure and intelligent processing for enterprise, data centre, cloud, wired and wireless networking, Cavium, has announced that its FastLinQ Ethernet 25/50GbE technology will power HPE Synergy480 and 660 Gen10 compute modules. The introduction for this new class of I/O connectivity for the HPE Synergy Gen 9 and Gen 10 compute modules provides density, cost and power benefits and enables acceleration ...
Buck-boost battery charge controllers enable USB Type-C support
A pair of highly flexible, single-chip buck-boost battery charge controllers for one- to four-cell (1S to 4S) designs has been introduced by Texas Instruments (TI). The bq25703A and bq25700A synchronous charge controllers support efficient charging through USB Type-C and other USB ports in end equipment ranging from notebooks and tablets to power banks, drones and smart home applications.
ESD-clamping diodes bring protection to smart objects
Miniature (0201-size) single-line ESD-protection diodes from STMicroelectronics quickly clamp transients to a voltage as low as 7V, and handle 7A peak pulse current, to provide superior protection and design flexibility for space-constrained smart objects. This diode drops the bar with the lowest clamping voltage available at this level of capacitance and stand-off voltage.
Slimline din rail power supply designed for worldwide use
A slimline, high-efficiency din rail product range up to 960W, which has been designed up to 30% smaller than the industry standard for industrial automation, control and instrumentation applications has been unveiled by Stadium Stontronics. With an input range of 90 – 264VAC, the product range is suitable for worldwide use.
300W output power modules suitable for use in data centres
New, higher power models have been added to TDK's PH-A280 series of high voltage input DC/DC converters. Capable of operating from 200-425VDC, these 300W output power modules are suitable for use in data centres, telecommunications and renewable energy applications utilising a 380V nominal high voltage DC bus. The four new models are rated at 12V 25A, 24V 12.5A, 28V 10.8A and 48V 6.3A. This extends the existing 50-150W PH-A280 product range ...
Buck battery charger provides seamless backup power
A complete lithium-ion battery backup management system for 3.45-4.45V supply rails that must be kept active during a long duration main power failure has been introduced by Analog Devices, which recently acquired Linear Technology. The LTC4091 employs a 36V monolithic buck converter with adaptive output control to provide power to a system load and enable high efficiency battery charging from the buck output.

Carrying medical safety approvals, the CX06M’s typical applications include clinical diagnostic equipment, medical lasers, dialysis equipment, radio-logical imaging and clinical chemistry. &nbs...
Electronic loads offer advanced and economical power supply testing
Enabling simple and economical testing of a wide range of power supplies, on-board chargers, batteries and other power electronics components, the new 63200E series high power DC electronic loads has been launched by Chroma. Available from MDL Technologies, the programmable loads offer market leading accuracies of up to 0.02% + 0.02% FS for voltage and 0.1% + 0.1% FS for current.
Fast 60V protected N-channel MOSFET Driver provides cycle capability
Analog Devices, who recently acquired Linear Technology Corporation, has announced the LTC7003, a high speed, high side N-channel MOSFET driver that operates up to a 60V supply voltage. Its internal charge pump fully enhances an external N-channel MOSFET switch, enabling it to remain on indefinitely. The LTC7003’s powerful 1Ω gate driver can easily drive large gate capacitance MOSFETs with very short transition times and 35ns pro...
