Increase Output Voltage With A Voltage Multiplier
17.04.2017 · Articles
Applications such as printers, laser-based fiber optic systems, and charged-particle air filtration systems require hundreds or even thousands of volts at low power. Flyback converters and autotransformer boosts are reasonable topology choices, but require custom transformers and require less-than-desirable high-voltage components...

17.04.2017 · News
ON Semiconductor has launched the FDMF8811, the industry's first 100 V Bridge Power Stage module for half-bridge and full-bridge isolated dc-dc converters. The 25 A-rated device integrates a 120 V driver IC, a bootstrap diode, and two highly efficient power MOSFETs in a PQFN-36 package...
High-Voltage Amplifier Extends Coulomb-Counter Range to ±270 V
14.04.2017 · Circuits
Low-range current measurement is a challenge when the associated voltage is relatively high, but a configuration of standard ICs meets the requirements. A coulomb counter can measure charge that flows into or out of a battery, and small, dedicated ICs can directly interface with low-to-medium battery voltages of up to about 20 V...

LED doubles as emitter and detector
12.04.2017 · Circuits
Every junction diode exhibits some degree of photosensitivity when it receives light comprising an appropriate range of wavelengths. The spectral response of a junction diode depends on a variety of factors, including material chemistry, junction depth, and packaging. The packaging of most devices aims to inhibit sensitivity to radiant flux to maintain the intended function of the device...
