LED buck driver handles 2 A, up to 65 V
Diodes Incorporated announces the expansion of its automotive-compliant* LED driver portfolio by introducing the AL8891Q. This easy-to-use synchronous Buck LED driver with high-side current sense drives up to 2A from a wide 4.5V to 65V input voltage range. It supports up to 95% duty cycle, allowing the drive of longer LED chains. The device provides […]
Surge protectors keep LEDs safe from lightning
Transtector has just introduced a new line of AC surge protectors for LED lighting and whole home surge protection. They are panel-style and rated to be located indoors or outdoors. The new AC SPDs (surge protective devices) feature a 25 kA/phase 8/20 µs lightning protection surge capacity that is ideal for LED lighting and whole home […]
Bipolar junction transistors show their muscle
Recent enhancements to the classic BJT show that the classic transistor has plenty of life left and can challenge SiC and GaN devices in some power applications. Amidst the advances in CMOS and wide bandgap semiconductor technology, you can easily forget that the first transistor invented by William Shockley in 1949 was a bipolar junction […]
Sink controllers request and control USB-C power
Diodes Incorporated releases two USB Type-C Power Delivery (PD) 3.1 extended power range (EPR) sink controllers. These can be embedded into battery-powered devices and other types of equipment using a USB Type-C socket as a power source, including routers, wireless speakers, power banks, and power tools. The AP33771C and AP33772S support product designers transitioning from proprietary charging ports, […]
15mm² active area silicon photodiodes for 300-560nm sensitivity
Marktech Optoelectronics has introduced new Series 4 silicon photodiodes with improved response speed. These photodiodes offer a response time of 25ns compared to the 80ns of current Series 4 PDs with the same active area. The new silicon photodiodes feature reduced junction capacitance (Cj), which improves response time, frequency response, and bandwidth. This is achieved […]
12-channel LED driver sinks 60 mA
Diodes Incorporated introduces a new 12-channel, constant-current LED driver, the AL58221. It features 12 open-drain outputs that are rated to 24V and sink up to 60mA of high-accuracy current with a fast transient response. The channel-to-channel LED current accuracy is typically ±1% and the regulated output current tolerance is ±0.1%. Operating over a 3V to 5.5V […]
Centralized LED drivers simplify large-scale lighting installations
Advanced Energy Industries, Inc. has announced the LumaDrive Pre-wired Systems series of high-efficiency remote centralized drivers for large-scale horticultural, greenhouse, and industrial LED lighting applications. These platforms combine multiple 4 kW modules into a cost-effective pre-wired cabinet that simplifies installation, enables simple “hot swap” repairs, eliminates extra dimming control connections, and reduces the overall cost […]
Switcher IC cuts need for second regulator, reducing board space
InnoMux2-EP switcher ICs for multi-output flyack power supplies eliminate the need for DC-DC post-regulators. A new design example report, DER-716, demonstrates the high level of integration realized by InnoMux2-EP devices. The single-stage power converter design is suitable for appliances and industrial power supplies. It features three constant voltage outputs (5 V, 12 V & 24 […]
PMIC and level shifter enhance IT display performance
Magnachip Mixed-Signal, Ltd. announced the release of a multi-functional Power Management Integrated Circuit (PMIC) and a multi-channel level shifter to regulate different voltages and signals within display panels in IT devices. As a subsidiary of Magnachip Semiconductor Corporation (“Magnachip”), MMS has been developing and supplying a wide range of power ICs, including backlight unit LED […]
