DC-DC converter handbook covers GaN transistors
The demand for information is growing at unprecedented rates and society’s insatiable appetite for communication, computing and downloading, is driving this demand. With emerging technologies, such as, cloud computing and the internet of things, not to mention the 300 hours of video being loaded to YouTube every minute, this trend for more and faster access […]
Diodes Incorporated enables cost-effective headset detection with low power IC in miniature package
The AZV5001 headset detection IC introduced by Diodes Incorporated is targeted at cost- and power-sensitive consumer electronics such as mobile phones, tablet computers and media players. The integration of a comparator, OR gate and N‑channel MOSFET into a miniature package enables the connection of a headset with microphone to be quickly and simply detected. The […]
Ultra low power switching regulators
For micropower applications there are some interesting new devices around for helping power the circuitry. I am not thinking here about energy harvesting applications but low power battery operated devices where you don’t want the battery to go flat quickly when in standby but still need some regulated power to wake up a microcontroller, for […]
Top power electronics threads on EDAboard.com – August
Phase shift full-bridge SMPS is massively over-hyped? – The Phase Shift Full Bridge (PSFB) converter is a hoax. The LTspice simulation (Editor’s note: see post for file) of a “plain” full-bridge SMPS bears this out. PSFB claims to be able to reduce switching losses compared to the “plain” full-bridge SMPS. However, the PSFB does have turn-OFF switching losses, just […]
Infineon Power MOSFETs Make Electrical Appliances More Compact and Durable
DIY tools such as cordless drills and saws have to be handy and durable. Therefore, the electronic components used in the applications need to be space-saving and rugged. Infineon Technologies AG has extended its StrongIRFET™ Power MOSFET family and thereby provides a solution that fulfills both requirements. The Logic Level StrongIRFETs™ can be driven directly […]
Power MOSFETs come in smaller packages
Fairchild, a global supplier of high-performance semiconductor solutions, launched its industry-leading mid-voltage MOSFET technology in a Dual Cool™ 8mm x 8mm package. The new Dual Cool 88 MOSFET gives power conversion engineers a first-of-its-kind alternative to bulky D2-PAK packages at half the size and with higher power density, superior efficiency and better cooling via air flow […]
