Darlington arrays drive big inductive losses
Higher performance, lower cost versions of the industry-standard ULN2000 series of Darlington arrays are now being offered by Diodes Inc. The modules integrate seven open-collector Darlington transistors, each capable of producing a high output current of 500mA, from outputs rated at 50V.
Synchronous buck regulators support auxiliary rails on FPGA platforms
Intersil has introduced 3Amp synchronous buck regulators for which it makes the claim that the devices will improve reliability and extend the life of end products. With integrated high side and low side MOSFETs, the new ISL85003/3A buck regulators support an input voltage range of 4.5V to 18V.
Innovative MOSFET design drives redundancy modules
There is a new MOSFET technology design at the heart of PULS YR-series of redundancy modules which are now available at BEC Distribution. These new DIN-Rail Power Supply Redundancy Modules are aimed at critical applications where failure of the 24V power supply is not tolerable, and redundancy - where two or more supplies are paralleled - is the preferred fail-safe solution.
Electrostatic screening probes boost accuracy
PCIM 2014: Wide-band screened CWT Mini Rogowski current probes from Power Electronic Measurements (PEM) use electrostatic screening strategy to enhance accuracy in the presence of large electrostatic interference signals. The shielding technique uses a low sensitivity coil and patented low-noise signal-conditioning circuitry.
Deliver 100W and data via a single standard USB port
Featuring an industry-standard power delivery and battery charging protocol, the UPD100X family of USB Power Delivery (UPD) controllers has been introduced by Microchip. 40 times the power compared to USB 2.0, a single USB cable can be used for data and simultaneously deliver up to 100W of power from a single standard USB port.
Power protection filters for military applications
Designed to protect downstream DC/DC converters in vehicle, mobile or avionic applications of up to 230W power rating, Stadium Power has introduced a range of military power system protection filters. The COBRA family consists of a range of low profile, PCB mounted, baseplate cooled, fully compliant surge and transient protection modules with integral EMC filter.
DC/DC converter series available with 24DVC & 48VDC inputs
A series of advanced DC/DC converter products has been introduced by Powerstax. The H0331 series is housed in the industry standard 1/2 brick packages format, with either 24VDC or 48VDC input buses, and are suited to industrial, telecommunications and data networking system applications.
VRLA batteries for standby power applications
Designed for use in standby power applications including telecommunications, datacentres and UPS, Yuasa Battery Sales introduce a range of valve regulated lead-acid (VRLA) batteries. The FXH series features front terminal connections for rapid installation and ease of maintenance when used in standard equipment racks.
90W adaptor is certified to IEC60601-1 & 2xMOPP
The GSM90B series, a high performance 90W desktop type medical adaptor, has been designed to fulfill the medical electrical device market’s demand for highly reliable power supplies. The adaptor series, from Mean Well, is certified with the third edition of IEC60601-1 and the design follows 2xMOPP (Means of Patient Protection).
Device provides 32 output voltages with no external resistor
A ULDO linear regulator has been launched by X-REL, signalling an expansion of the company's power management portfolio. The XTR70010 high current, linear regulator has been designed for high-reliability, extreme temperature and extended lifetime power supply applications and can provide 32 different output voltages with no external resistor. The device can also operate as a capacitor-less regulator in applications where the output current does n...
