Rohm is claiming “industry’s first high-speed op-amp that eliminates oscillation due to load capacitances” for its 10V/μs BD77501G – which is not quite true unless some further caveats are added as, for example, ADI’s ‘C-Load’ op-amps are stable with any capacitance – LT1364 can hit 1,000V/μs. Rohm’s branding for capacitive tolerance is ‘Nano Cap’. BD77501G is ...

Artificial intelligence that tricks you into paying more for things has come under the academic spotlight in a project by Swiss lab EPFL and British partners. The research into unethical AI is from the point of view of companies that do not want their AI to give them a reputation for tricking people. It finds ...

US researchers have manipulated fixed magnetic skyrmions using voltages, offering a possible route to skyrmion memory. Magnetic skyrmions are self-contained stable spin fields that share some characteristics with particles. They can be only a few nanometres across, and in certain circumstances can be created, destroyed and manipulated with very little energy, leading to them being ...

STMicroelectronics has announced a power-factor correction controller for the front-end of ac-dc PSUs from 600W to 6kW. Called STNRGPF02, it implements a two-channel interleaved boost topology as well as in-rush current limiting. Operation is fixed-frequency continuous-conduction mode (CCM) with average current-mode control. “A blend of analogue and digital control combines a hardware analogue PI [proportional-integral] ...

Diodes is aiming at automotive point-of-load converters with a 1A buck converter that can run from 5V and 3.3V rails. Output can span 600mV to 3.6V said the company, although one data brief says 800mV to 4V. Called AP61100Q, the chip has synchronous rectification – with a 110mΩ high-side mosfet and 80mΩ low-side mosfet. Operation ...

Frontier is aiming at better-looking DAB+ radio products with a ‘Pro’ range of chips, modules and software. Its Kino 4-Pro chip has a larger memory than its earlier silicon, allowing features to be added without compromising performance. Siena-Pro is a module built around Kino 4-Pro. To ease migration, Kino 4-Pro and Siena-Pro are pin compatible ...

Toshiba has introduced a pair of fast opto-couplers that will work from 2.2V, allowing them to work from the 2.5V rail of LVCMOS, for example, as well as up to 5.5V. Typical 3.3V data rates are: TLP2312 5Mbit/s TLP2372 20Mbit/s The threshold input current of 1.6mAmax and the supply current of 0.5mAmax at entire operating temperature ...

Adam Tech Interconnects has created waterproof spring-loaded ‘pogo’ pins. Such pins, soldered through one PCB, allow them to connect to copper pads on another PCB, or to other conductive objects, with some tolerance to mating distance variation. “These DIP Pins are designed with an inner rubber seal and offer an IP rating to prevent moisture ...
