Isolated gate driver maximises SiC switch benefits
Driving high efficiency Silicon Carbide (SiC) and traditional silicon power switches, HADES is a 2nd generation isolated gate driver chipset. CISSOID's latest offering aims to maximise the benefits of the newest Silicon Carbide (SiC) power switches. To accomplish this, increased switching frequencies translate into dramatic reduction of the size & weight of the passive & magnetic components; while faster switching times lead to increased ...
Adaptive-Dead-Time circuitry maximises MOSFET power efficiency
Featuring Adaptive-Dead-Time and Shoot-Through protection, the MIC4605 is an 85V Half Bridge MOSFET driver from Micrel. By actively monitoring the Half Bridge, the Adaptive-Dead-Time circuitry can minimise the time between high and low side MOSFET transitions to increase the power efficiency, while the Anti-Shoot-Through circuitry prevents erroneous inputs and noise from turning both MOSFETs on at the same time.
Transformer rectifiers deliver conversion efficiencies of up to 96%
Benefiting from added technical expertise following their aquisition of Drake Power, Powerstax have announced additional offerings to their transformer rectifier portfolio. The Powerstax transformer rectifiers support conversion efficiencies reaching 96% and typical power factors of 0.85, or as much as 0.99 if extensive power factor correction is applied.
AC-DC power supply series expands with 130W addition
Packaged in a compact 50.8 x 101.6 x 31.8 mm (2 x 4 x 1.25 inch) open-frame format, the single output ECS130 signals the latest addition to XP Power's ECS series of AC-DC power supplies. The series comprises 6 single output models providing the popular nominal output voltages from +12 to +48 VDC. The extra wide input accommodates the full universal voltage range from 80 – 264 VAC.
Harmonic filters designed for “out of reach” locations
Designed to meet IEEE-519, the PB-W (Wall-Mount) Series of three-wire and four-wire active (3x200VAC to 3x480VAC) harmonic filter modular systems has been announced by Schaefer. The systems are scalable, with the wall-mount versions designed for mounting in small and confined areas, as well as required “out of reach” locations.
Adapter boasts thinnest and smallest 45W design
Allowing for less than one-half the overall volume and claiming to be 50% thinner than conventional 45W adapters, Dialog's 45W power adapter has been released alongside a 12W travel-size power adapter. Designed for use with Ultrabooks, the 12W design enables the first compact, pocket-size adapters for an Ultrabook at just 68mm x 68mm x 17mm thick, with a typical charge time under five hours.
Diode bridge for universal PoE applications up to 51W
The PD70224 IdealPoE diode bridge is a dual pack of MOSFET-based full-bridge rectifiers from Microsemi. Integrating low-RDS 0.16Ohm N-channel MOSFETS for much higher overall efficiency and higher output power, this power solution is suitable for use in powered devices for PoE and PoH (Power-over-HDBaseT) applications in the communications and enterprise markets, including wireless LAN access points, small cells and small switches/routers.
AC/DC enclosed type power supply meets medical requirements
In response to the high wattage requirement of reliable medical power supplies MEAN WELL have announced the MSP-600 series of 600W AC/DC medical enclosed type power supplies. With low leakage current of less than 300μA at 264V ac the power supplies are suited for non-patient contact medical applications.
1W DC/DC converters suit industrial automation
Designed specifically for use in industrial, automation and instrumentation applications, the MEF1 series of 1 Watt regulated DC/DC converters have been introduced by Murata Power Solutions. The single rail regulated output makes the converters ideal choice for power sensors, such as pressure transducers, hall effect sensors and mass airflow sensors.
Low noise block regulators for STBs and LCD TVs
Expanding the company's extensive portfolio of low noise block (LNB) regulators designed for satellite receivers in Set Top Boxes and LCD TVs, Allegro Microsystems has introduced the A8300 and A8300-1. Fully integrated linear and switching voltage regulators, they are specifically designed to provide the power and interface signals to an LNB down-converter via coaxial cable.
