UC3844AD8G4 Overview


Capsuled in the 8-SOIC (0.154, 3.90mm Width) package, the switching controller suits most application needs. The dc motor controller is adquate to generate for 1 outputs. The pmic is packaged in Tube solid enclosure. A total of Transistor Driver dc switching's outputs can be handled by it. This dc control operates at 10V~30V and has a 10V~30V supply voltage. Qualified to work in an dc switcher with 0°C~70°C TA. The switching controller is capable of switching at the Up to 500kHz position. The Surface Mount makes it ideal for general dc dc regulator. DCDC regulator is controlled efficiently by Frequency Control. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. DUAL are the position of the terminal of the switching converters. A variety of dc switching's functions can be performed on 8 terminations. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. The DC switcher's nominal voltage is 15V. You can find other relevant dc to dc converter ics by searching "UC3844". The switching converter has a total of 8 pins. Switching converter is a type of Switching Regulator or Controllers in particular. The test statistics indicate that DC regulator outputs a voltage of 15V. It's important to remember that the dc dc regulator's normaloutput current is 200mA, so you should note it down when starting a new project. Voltage regulator dc to dc is designed to operate at 50 % duty cycle during power-ups and power-downs to ensure reliability. There is 450kHz frequency setting on the switching controller. 25V is the nominal working voltage. There must be a voltage supply of 11V volts. Current supplied to the controller should not exceed 25mA.
