Power-management ICs optimized for use in laptops
MagnaChip Semiconductor Corporation announced a new line of power management integrated circuits (PMIC) by introducing its first UHD display panel PMIC for laptops. PMICs are integrated circuits that include multiple power management functions within a single chip, and they are frequently used to power space-constrained devices where high-efficient and compact form factors are required. They […]
Project: Implementing a 4xN LED driver
by Dialog Semiconductor LED displays are widely used in systems ranging from digital clocks, counters, timers, electronic meters, basic calculators, and other electronic devices capable of displaying numerical information. Figure 1 depicts an example of a 7-segment LED display which can show decimal numbers and characters. As each segment on the LED display can be […]
Want to kill Covid? 30 sec under 285-nm UV-LEDs will do it
Researchers from Tel Aviv University found that UV light at a wavelength of 285 nm was almost as efficient in disinfecting the Covid virus as a wavelength of 265 nm, requiring less than half a minute to destroy more than 99.9% of the coronaviruses. They say this result is significant because the cost of 285-nm […]

Bidirectional buck-boost, dual-phase buck DC/DC controllers handle 48-V apps
The ISL81801 buck-boost controller acts as a “UPS on a chip” by enabling bidirectional current flow (forward or reverse) using constant-voltage and constant-current regulation. This allows a battery or supercapacitor to be charged and discharged using a single controller and power path. The ISL81801’s combination of the industry’s highest 80V buck-boost switching frequency (600 kHz) […]
