SMART ALGORITHM TRIPLES SERVICE LIFE OF POWER SUPPLIES
New modulation method increases operational lifetime of switching power units through digital, highly dynamic control and the use of film capacitors. SMART ALGORITHM TRIPLES SERVICE LIFE OF POWER SUPPLIES Switching power units are used for the power supply of many electrical devices, e.g. computers, LED lights or laser welding equipment. They convert alternating current from

Sine wave oscillator using LM741
The oscillators are the devices that generate oscillatory (AC) output from given DC input. There are different kinds of oscillators based on the output waveform they generate. Like · Sinusoidal oscillators – they generate sinusoidal (sine) wave output · Square wave oscillators – they generate square (or rectangular) wave output · Triangular wave oscillators –

ULTRA-LOW QUIESCENT LDO EXTENDS BATTERY LIFE FOR SENSORS AND PORTABLE DESIGNS
With ultra-low quiescent current of 250 nA, the MCP1811 enables battery life which is four-times longer than conventional ultra-low Iq LDO regulators. Compact packages down to 1 x 1 mm also help the MCP1811 to minimise board space. The MCP1811/12 devices are 150 mA (MCP1811) and 300 mA (MCP1812) low dropout (LDO) linear regulators that provide high-current and low-output
