Intersil claims to have smallest pico-projector

Description The ISL9307 is an integrated mini Power Management IC (mini-PMIC) ideal for applications for powering low-voltage microprocessor or multiple voltage rails with a battery as an input source, such as a single Li-ion or Li-polymer. ISL9307 integrates two high-efficiency, 3MHz, synchronous step-down converters (DCD1 and DCD2) and two low-input, low-dropout linear regulators (LDO1 and […]

Energy Wristband

Energy Wristband

Introducing… the Energy Wristband A wristband that tells you energy changes in your home. It connects via a Raspberry Pi computer to a base station like a‘current cost’ or similar. When a change in energy usage occurs, the wristband vibrates and a small LED bargraph shows your current usage from 1 to 4. Realtime energy

Buckyballs and diamondoids combined to create molecule sized diode

Buckyballs and diamondoids combined to create molecule-sized diode

Scientists working at the Stanford Institute for Materials and Energy Sciences (SIMES) claim to have created a molecule-sized electronic component just a few nanometers long that conducts electricity in only the one direction. In essence, a rectifier diode, but one so small that it may one day help replace much bulkier diodes and other semiconductors

2 NEW FAMILIES FROM MICROCHIP

2 NEW FAMILIES FROM MICROCHIP

Microchip has introduced two new 8-bit MCU families with integrated Core Independent Peripherals (CIPs). You may be thinking that 8-bit processors are unlikely to cut the mustard for many of today’s applications but built-in interconnected CIPs combine to perform functions autonomously, without intervention from the processor. This makes these new 8-bit families suitable for a

Low-loss Step-down Regulator

Adding to their ever growing family of power supply regulators Linear Technology have introduced the LTC3807 step-down switching regulator DC/DC controller driving an all N-channel external synchronous power MOSFET stage. The chip uses a constant frequency current mode architecture allowing a phase-lockable frequency of up to 750 kHz. The chip draws just 50 μA no-load quiescent current
