Transformer drivers enable compact, low-noise isolated power supplies
Nexperia introduced the NXF6501-Q100, NXF6505A-Q100, and NXF6505B-Q100. These are AEC-Q100 qualified, push-pull transformer drivers that enable the design of small, low-noise, and low-EMI isolated power supplies for a range of automotive applications like traction inverters and motor control, DC-DC converters, battery management systems and on-board chargers in electric vehicles (EV). These transformer drivers are also […]
Low noise, high voltage chip dividers now available up to 4KV
High voltage applications frequently require high resistance value resistors with the ability to handle high working and overload voltages. Engineers may have difficulty finding thick film chip resistors with the required precision for applications requiring tight resistance tolerance and TCR tracking. For precision high-voltage applications, a high-voltage divider chip can be beneficial. Stackpole’s new HVCD […]
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 […]
240 W eval board targets gains in USB-C power delivery
Eggtronic has unveiled an evaluation board (EVB) that allows engineers to speed the development and significantly reduce the size and cost of 240W power delivery (PD) 3.1 applications while supporting ultra-fast charging through industry-leading efficiency. The SmartEgg 240W PD 3.1 EVB has a peak efficiency above 95% and operates at over 90% efficiency from light […]
Power device portfolio expanded with low-Ohmic, high-current eFuse
Nexperia announced the NPS3102A and NPS3102B electronic fuses (eFuses) as the latest additions to its ever-expanding power device portfolio. These low-ohmic (17 mΩ), high current (13.5 A), and resettable electronic fuses help to protect downstream loads from exposure to excessive voltages while also protecting power supplies from load faults and large inrush currents. These eFuses […]
