IGBT modules suit industrial applications
The ACEPACK IGBT modules from STMicroelectronics (ST) are in stock at Mouser Electronics. Part of a new plastic power module family developed mainly to address industrial applications, the Adaptable Compact Easier PACKage (ACEPACK) modules provide economical and highly integrated power conversion for 3kW – 30kW industrial and power management solutions.
Boost regulator designed for low voltage optical systems
Analog Devices hasannounced the Power by LinearLTM4661, a low power step-up µModuleregulator in a 6.25x6.25x2.42mm BGA package. Only a few capacitors and one resistor are required to complete the design, and the solution occupies less than 1cm² single-sided or 0.5cm² on double-sided PCBs. The LTM4661 incorporates a switching DC/DC controller, MOSFETs, inductors and supporting components. The LTM4661 operates from a 1.8-5.5V input ...
Synchronous rectifier controller delivers higher efficiency
Continuing its strategy to meet the industry-wide demand for increased power density and improved efficiency, Diodes Incorporated has introduced the ZXGD3113 synchronous rectifier controller. When coupled with a MOSFET, the pairing can be used to replace lossy Schottky rectifiers in power supplies based on a flyback or resonant converter topology.
TVS diode protection for VFDs/IGBT inverters
In virtually all industrial control systems, variable frequency drives (VFDs)/ inverters are commonly installed at the front end of motors in order to regulate speed and save energy. Based on differing input voltage requirements, inverters are often categorised as low voltage (110, 220 and 380V), medium voltage (690, 1140 and 2300V), or high voltage (3, 3.3, 6, 6.6 and 10kV).
The efficient redundancy for power supplies
Maximilian Hülsebuschfrom PULS here reviews advances in reliable power system availability in the event of a short circuit.N+1 redundant power module connection guarantees reliable system availability even if a power supply fails. However, the common use of decoupling diodes in such modules causes a large voltage drop leading to high power losses generating heat.
TVS diode arrays protect I/O and power ports from ESD
Littelfuse, Inc. has introduced two series of AEC-Q101-qualified, unidirectional TVS Diode Arrays optimised to protect I/O and power ports against electrostatic discharges (ESDs). SP1053 and SP1054 Series TVS Diode Arrays (SPA Diodes) integrate avalanche breakdown diodes fabricated using proprietary silicon avalanche technology to protect each pin.
Diodes protect USB and power supply interfaces in mobile devices
Toshiba Electronics has announceda new series of TVS diodes that protect USB power lines and power supply connectors used in mobile devices.Toshiba’sDF2SxxP2 seriesprotects the power lines of smartphones and tablets by suppressing malfunctions and damage from ESD, noise from induced lightning that enters via the power cord and signal cable, and transient voltage at the time of turning equipment on or off.
SiC diodes offer higher efficiency and lower system costs
With the introduction of a new family of 650V silicon carbide (SiC) Schottky diodes,ON Semiconductorhas extended its SiC diode portfolio. The diodes’ silicon carbide technology provideshigher switching capabilities with lower power losses and supposedly effortless paralleling of devices.
Radiation tolerant eight-channel source driver for space programmes
Microsemi has announced its radiation-tolerant AAHS298B eight-channel source driver for space applications, which has been successfully qualified and certified by the US Defense Logistics Agency (DLA) as Qualified Manufacturers List (QML) Class V and Q, with four Standard Microcircuits Drawings (SMDs) listed, is now in production.
Microprocessor circuit monitors voltage with programmable delay
The PT7M3808 family of microprocessor supervisory circuits introduced by Diodes Incorporated monitors system voltages from 0.4-5.0V. With threshold accuracy from 0.5% and an adjustable delay time from 1.25-10ms, these small form-factor devices enable power-on reset functionality for microprocessor and other digital systems while consuming minimal power.
