Microsemi Unveil Linear POL Regulators For Space, Aviation And Defence Applications
The MHL8701 and MHL8705 ultra-low dropout linear point-of-load regulators for space, commercial aviation and defence applications have been introduced by Microsemi. The first devices of their kind to do so, the radiation-hardened MHL8701 and MHL8705 regulators include an integrated single event effects filter to protect against soft errors caused by heavy ions often found in air- and space-borne applications.
Synchronous buck regulator IC for automotive applications
The new A8650 from Allegro MicroSystems Europe is a robust synchronous buck regulator IC designed for automotive power-supply applications in areas such as instrument clusters, HVAC, navigation, and audio systems.
Eltek Sets New Standard in Power Density with Flatpack S 1800W Rectifier
Eltek today announced an extension to the Flatpack S family with the launch of Flatpack S 48V/1800W HE. The Flatpack S family is designed to fit into applications with limited depth or limited space.
Keep Hybrid Powertrain Drives Noise Free By Rejecting dV/dt Noise With Isolated-Gate Drivers
High common-mode noise is a significant problem that automotive system designers must overcome when designing a practical and reliable powertrain drive system. Common-mode noise (also known as dV/dt noise) is generated naturally within a system when there is high-frequency switching in the high-voltage power inverters and other power supplies. This article will discuss the various sources of dV/dt noise in a hybrid powertrain drive and suggest se...
The BVN precision resistor uses 25 per cent less space and is ideal for installation on DCB ceramics
Isabellenhütte has added the new BVN four-terminal resistor to its measuring resistor range. It is exceptional due to its small size of between 3.3 and 4 millimetres plus its extremely low temperature coefficient of less than 50 ppm/K. “It is difficult to produce low-ohmic resistors with values of less than 1 mOhm that also have good temperature coefficients. The BVN has achieved it – together with a size that is 25 per cent smal...
ALD EPAD MOSFET Arrays Introduce Revolutionary Control of Independent Devices
Advanced Linear Devices today announced an industry breakthrough in small signal, precision matched, low power MOSFETs by enabling independent control of each device within a quad package. This innovative capability will provide circuit designers with unprecedented flexibility in developing next-generation energy harvesting systems and low-power mobile devices.
Power supply for parallel support of mainboard and display
The new power supply BEG-300-1224 with dual output by Bicker Elektronik, Donauwörth, provides +12VDC and +24VDC output voltage, thus enabling a simultaneous supply of the mainboard (+12V) and a second device such as display, printer or coin validator.
Fanless 40 W power supply for medical and industrial use
With the introduction of the new BEO-0400M, Bicker Elektronik, Donauwörth, extends its successful BEO series of power supplies in the lower performance range up to 40 watts. The nine different models of the BEO-0400M are available with output voltages from +3,3V to +48V.
