All electronics projects need power. Power can come from either stored energy in a battery, or directly from mains AC voltage or DC power from renewable sources such as solar energy. Power Management ICs (PMICs) help manage the power requirements in a system including scaling voltages, battery charging, and DC-DC conversion. Choosing the right PMIC …
Microchip introduced a new 64Mbit Serial Quad I/O™ memory device—SST26WF064C with proprietary Super Flash® technology. The SST26WF064C writes with a single power supply of 1.65-1.95V and significantly lower power consumption. This makes it ideal for wireless, mobile, and battery-powered applications. This 64Mbit memory device also features DTR or Dual Transfer Rate technology. DTR lets the user access data of the …

Engineers at the University of Bristol have developed a three terminal pico-power chip that can cut standby drain in sensor nodes – even compared with today’s low-power microcontrollers. It does this by replacing the low duty-cycle sleep-wake-sleep pattern used on MCU-based sensor monitors, with ‘off’. A voltage detector powered by the sensor – there is …

A recent eBay fishing expedition yielded an interesting little part for the very reasonable sum of about five pounds. It’s a voltage regulator module from a Dell PowerEdge 6650 Xeon server. I originally bought this because I had the idea of salvaging parts from it to use in another project. These are high quality modules …

Introduction: A voltage step-up is a circuit that increases the voltage. It can be AC/AC, AC/DC, DC/AC or DC/DC. This voltage step-up is a DC/DC adjustable voltage regulator. Usually a voltage regulator is fed by a higher input than output voltage, for example 9V IN to 5V OUT. This circuit will take a low voltage …

Whether for driving white LED backlights or powering RF and analog circuits, laptops, tablets and other mobile devices often require voltages that are much higher than the input supply voltage. Consequently, step-up or boost DC/DC converters generate output voltages that are several times the input to serve a variety of circuits and functions in these …
