What is the Pocket Voltage Supply and What Makes it Interesting? The Pocket Voltage Supply is a USB powered variable voltage supply. It can be powered with any 5V USB hub and can supply up to 1.5A. 5V USB hubs can be found almost anywhere; desktop computers, laptops, cell phone chargers, even portable USB battery banks. Pairing the […]

Such is the popularity of DC-to-DC voltage converters (“switching regulators”)––due to their high efficiency across wide input- and output-voltage ranges––that chip makers have focused a lot of research dollars on squeezing the essential components of the devices into modules. These modules typically include pulse-width-modulation (PWM) controllers and switching elements in a single, compact package, easing

Micrel Inc. introduced the MIC28511/12/13, a family of pin-compatible high voltage (HV) synchronous step-down switching regulators with integrated power switches capable of providing up to 4 A (MIC28513) output current and a wide input supply range from 4.6 V to 70 V. The MIC28511/12/13 are offered in both Hyper Speed Control™ and HyperLight Load® architectures,
Description 0-10V Volt monitor project has been designed around LM3914 IC, It is an easy and less expensive project which instantly visualizes voltage level. The project is based on the popular LM3194 IC from Texas instruments. Handy 0-10V DC Voltmeter can be used as a voltage tester. The LM3914 senses the voltage level at the

After my recent posts on using the MCP23017 I/O expander with the Raspberry Pi several people have queried the connection of an I2C device running at 5v to the Raspberry Pi’s 3v3 I/O. The reason why this is safe in this case is that on an I2C bus the clock and data lines are open-drain
