Alex Lidow from EPC recently did a short video with us covering a brand new GaN-DC/DC converter that’s super small and efficient. Lidow says EPC has been working to improve GaN-based dc/dc conversion for about eight years. They had to overcome a lot of barriers to do so because when they first started, there were […]
Eval kits help design silicon-carbide power circuits
There’s a lot of benefits that come with silicon carbide semiconductor devices. Increased power density, increased efficiency, lower form factor, simpler designs, simpler thermal management, are all examples of the benefits. But along with the things that silicon carbide enables, there’s also some side effects that make them hard to control, and if they’re not […]

Toshiba Electronic Devices & Storage Corporation announces the availability of a new compact power MOSFET gate driver intelligent power device (IPD) for automotive 3-phase brushless motors. The device is intended for use in automotive motor drive applications, such as 12V electronic power steering (EPS), oil/ water pumps, fan motors and electric turbochargers. Toshiba’s IPD products […]
MOSFET driver delivers 5V to 20V DC from an AC supply
Diodes Incorporated announced the APR346 secondary side synchronous rectification MOSFET driver, providing increased efficiency for off-line power adapters delivering 5V to 20V DC from an AC supply. Designed to operate in Continuous Conduction Mode (CCM), Discontinuous Conduction Mode (DCM) and Quasi-Resonant mode (QR), the APR346 is used to drive an external MOSFET to deliver the benefits […]
600-V MOSFET combined with 650-V Schottky diode in top-side cooled surface-mount package
Increasing complexity of end products is challenging the design parameters for high power supplies: these require higher power and more efficiency in an even smaller space. Semiconductor devices are essential to the operation and performance of modern switched mode power supplies (SMPS). Over the last years, a trend towards surface mount devices (SMD) has been emerging. […]
Intelligent power modules incorporate MOSFETs with low conduction and switching losses
Global energy efficiency standards often prohibit manufacturers from importing or selling products that do not meet these standards. In order to comply with specific minimum requirements, energy losses have to be reduced by using the latest technology. Infineon Technologies offers the IM512 and IM513 series of the CIPOS Mini family. They are the first high […]
Low RDSon SiC MOSFET power modules in SP6LI package offers 2.9 nH stray inductance
Microsemi Corporation announced its extremely low inductance package dedicated to high current, low specific on-resistance (RDSon) Silicon Carbide (SiC) MOSFET power modules. The new package, developed specifically for the company’s SP6LI product family, is designed to offer 2.9 nanohenry (nH) stray inductance suitable for SiC MOSFET technology and enable high current, high switching frequency as […]
3-kW 3-phase PFC reference design uses SiC diodes and MOSFETs
Microsemi Corporation announced the availability of its new scalable 30-kilowatt (kW), three-phase Vienna power factor correction (PFC) topology reference design featuring its Silicon Carbide (SiC) diodes and MOSFETS. Developed in collaboration with North Carolina State University (NCSU), the scalable, user-friendly solution is ideally suited for fast electric vehicle (EV) charging and other high power automotive and industrial applications, providing customers with more efficient switching […]
Single-channel IGBT/MOSFET gate-driver ICs get UL 1577 certification
Infineon Technologies AG now offers the EiceDRIVER 1EDC Compact 300 mil family of single channel gate driver ICs. With an insulation test voltage of V ISO = 2500 V(rms) for 60 sec these galvanically isolated drivers are recognized under UL 1577. Due to their high switching frequency of up to 1,000 kHz they do not only drive IGBTs, […]
IGBT, MOSFET drivers get protective conformal coating
Power Integrations today introduced factory conformal coating for its SCALE IGBT and MOSFET drivers. Conformal coating enhances system reliability by protecting electronic components against contaminants such as pollution, dust and condensation, which may cause corrosion. Power Integrations’ factory-coated gate drivers reduce inventory cost, lead time and overall cost of ownership by eliminating the need for […]
