LITIX TM Basic TLD1313EL is a three-channel high-side drive INTEGRATED circuit with integrated output levels. The device is designed to control leds with currents up to 120 mA. In typical automotive applications, the device is capable of driving three (nine leds in total) red leds with currents up to 60mA per channel, with current capacity …
The L6572 is a high voltage half-bridge driver for current regulating, quasi-self-excited oscillating ballasts. It contains all the functions necessary for preheating the filament, igniting and operating the fluorescent lamp. During normal operation of the lamp, the ballast operates with a nominal or reduced resonant current, resulting in a nominal or reduced light output of …
According to NHK, Japan's Ministry of Economy, Trade and Industry (METI) recently said that Japan will vigorously develop new energy and battery industries targeting China and South Korea in the future. It plans to increase Japan's battery production capacity to 600GWh by 2030, accounting for 20% of the global market share. At a recent meeting …
Nowadays, young people of both sexes have more diversified and richer demands for mobile phones.
