LED drivers in ultra-low profile suitable for LED edge-lighting
In response to growing demand for smaller LED lighting installations that also provide high efficiency and ultra-low EMI, Diodes Incorporated has extended its popular BCR420U and BCR421U families of linear LED drivers to include the BCR420UFD and BCR421UFD devices in the ultra-low profile DFN2020 package, making them well-suited for 12V and 24V LED edge-lighting applications. […]
Auto-grade regulator transistors tolerate 60-V battery transients
The ZXTR2105FQ, ZXTR2108FQ () and ZXTR2112FQ regulator transistors announced by Diodes Incorporated are qualified to AEC-Q101 standards for high reliability and are product part approval process (PPAP)-capable. Designed to deliver 5V, 8V, or 12V regulated outputs from nominal battery supplies of 12V or 24V, these regulator transistors are well-suited for powering vehicle electronics. These devices can […]
A simple and inexpensive ideal-diode MOSFET circuit
by Crutschow When you parallel a battery with another battery or other source, the batteries are often required to be back charged. This can be done with standard diodes, but that gives close to a half volt drop — even with Schottky diodes. This is especially problematic with low-voltage batteries, where that drop is a […]
Drivers targeted at 12V and 24V linear LED strips
Appealing to lighting designers, the BCR401U, BCR402U and BCR405U constant current regulators introduced by Diodes Incorporated enable simple driving of low-current LED strips and panels in the commercial and industrial lighting sectors. Targeted at 12V and 24V linear LED strips, these regulators increase light output efficiency as they only require a 1.4V supply, allowing more […]
OR’ing MOSFET controller supports power supplies up to 400V
Extending the capability to support redundancy power systems with rail voltages up to 400V, the ZXGD3112N7 active OR’ing MOSFET controller introduced by Diodes Incorporated, builds on a successful design employed in previous 40V and 200V devices. A low turn-off threshold voltage enables very low RDS(on) MOSFETs to operate as ideal diodes, providing a highly efficient […]
Automotive-compliant power ICs launching at Embedded World
Diodes Incorporated will be introducing a number of notable new products at Embedded World 2017 in Nuremberg, Germany, March 14-16. These include the industry’s first unidirectional 1800W automotive-compliant transient voltage suppressors; 40V and 60V dual, co-packaged enhancement mode MOSFETs that are also qualified for automotive applications; and, coming from its Pericom connectivity product line, the […]
AECQ100-qualified Hall Effect ICs offer 30G BOP to 275G BOP switching sensitivities
Targeting automotive applications, Diodes Incorporated has introduced a new family of high-voltage, unipolar Hall effect switch ICs that are qualified to AECQ100 Grade 0 and offer a range of operating sensitivities. Designed for position and proximity sensing in applications such as seat buckle fastening, door, and trunk open, close and lock function detection, and the […]
Triac-dimmable LED controller/driver design platform drives LED lamps up to 25W
The AL1692 LED controller/driver introduced by Diodes Incorporated is a platform-based design solution for triac-dimmable LED lamps. The internal MOSFET versions provide a low-cost solution with compact PCB size and directly drive lamps rated from 3W to 13W. The controller-only version with an external MOSFET can support higher power applications up to 25W. Intended for […]
More power IC technologies challenge design decisions
By Roger Allan, contributing writer There’s good news for power supply system designers. Silicon-based power devices are making performance advances in diode, transistor, and field-effect transistor (FET) functions. But wide-bandgap semiconductor IC technologies like gallium nitride (GaN) and silicon carbide (SiC) are poised to grow rapidly, offering designers greater performance in a smaller package, making […]
