UC3844AD8TR Product Details

UC3844AD8TR Overview


This switching controller fits most application requirements since it is packaged in a 8-SOIC (0.154, 3.90mm Width) package. The dc motor controller is adquate to generate for 1 outputs. Packaged in solid enclosures, this pmic has a Tape & Reel (TR) rating. The system can process Transistor Driver dc switching's outputs (s). dc control's supply and operating voltages are 10V~30V. Qualified to work in a 0°C~70°C TA dc switcher. There is a switch at Up to 500kHz that can be used with this controller. A generalization of dc dc regulator can be made using Surface Mount. In order to control switching efficiently, the dcdc regulator features Frequency Control. Switch converters are connected to ICs with SWITCHING CONTROLLER analog outputs. The switching converters's terminal (s) are designed at DUAL . There are many different types of terminations for 8. PULSE WIDTH MODULATION is an example of one of the control techniques these dc dc converter ics adapt. A DC switcher's nominal voltage of 15V is input. A search for "UC3844" will reveal other relevant dc to dc converter ics. There are a total of 8 pins on switching converter. Switching converter is a type of Switching Regulator or Controllers in particular. Statistically, DC regulator outputs 15V volts. The dc dc regulator's usual output current is 200mA, which should be noted down when you start a project. A duty cycle set at 50 % ensures voltage regulator dc to dc reliability during power-on and power-off. Switching controller operates at 450kHz Hz. For nominal working status, the input voltage can be set as 25V. Switching controller is necessary to provide a voltage of 11V. You should not supply more current than 25mA to the controller.
