Reducing ringing or reflections by controlling impedance lines
What is a controlled impedance line? For one thing, the term has to do with Printed Circuit Board (PCB) traces and layouts, which get more complex with higher frequency signals. Generally, you need not worry much about controlling impedance in traces unless you are working with signals at or above 50 MHz. However, most of […]
60 V/1A buck LED driver adds dimming for commercial lighting
A wide input voltage range and integrated power MOSFET make the AL8862 buck LED driver a solution well-suited for developers of LED lighting drive circuits looking to minimize board space and reduce BoM cost with excellent analog and PWM dimming functions. With a typical output current accuracy of 5% at up to 1A and 97% […]
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. […]
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 […]
2.0A, 2.5A and 3.0A power switches optimized for USB port protection
Featuring an ultra-low on resistance to reduce power losses, the AP22811 and AP22804/AP22814 power switches introduced by Diodes Incorporated are optimized for universal serial bus (USB) and other hot-swap applications. Supporting load currents of 2.0A, 2.5A and 3.0A, respectively, this family of devices protects USB ports against over-current, short-circuit and over-temperature conditions and prevents system […]
