DipTrace is a sophisticated schematic and PCB layout software. I had it installed on my computer for over a year but have never really used it. Since I needed a super simple PCB for some 78XX / 79XX type linear regulators, I decided to use this opportunity for my first steps with DipTrace. DipTrace offers […]

Introduction Driven by the need for untethered mobility and ease of use, many systems rely on rechargable bat- teries as their primary power source. The battery charging circuitry for th ese systems is typically implemented using a fixed- function IC to control the charging current/voltage profile. The C8051F30x family provides a flexible alterna- tive to

Determine the power absorbed by the VCVS in the figure. Solution: The VCVS consists of an open circuit and a controlled-voltage source. There is no current in the open circuit, so no power is absorbed by the open circuit. The voltage vc across the open circuit is the controlling signal of the VCVS. The voltage Vc

In July 2015, Intel and Micron Technology announced a new technology for memory and storage solutions called “3D XPoint™ technology“. It is a new category of nonvolatile memory that addresses the need for high-performance, high-endurance, and high-capacity memory and storage. Now Intel had produced its Optane™ technology that provides an unparalleled combination of high throughput, low latency, high quality of service, and high endurance. The new technology

Analog Devices announces the Power by Linear™ LTC3777, a 150V high efficiency (up to 99%) 4-switch synchronous buck-boost DC/DC controller, which operates from input voltages above, below or equal to the regulated output voltage. Its 4.5V to 150V input voltage range operates from a high input voltage source or from an input that has high
Description USB Power Delivery is a cool standard for getting lots of power—up to 100 W—from a USB Type-C port. Being an open standard for supplying enough power to charge phones, laptops, and just about anything else under the sun, USB PD is poised to greatly reduce the amount of e-waste produced worldwide from obsolete
