UC3845BD1R2G Overview

Capsuled in the 8-SOIC (0.154, 3.90mm Width) package, the switching controller can be used for a wide range of applications. There is enough capacity in the dc motor controller to generate the output for the 1 input. PMIC packaging is solid with a Tape & Reel (TR) enclosure. A total of Transistor Driver dc switching's outputs can be handled by it. Voltages 7.6V~30V are the dc control's supply voltage and operating voltage, respectively. Work well in dc switchers with a 0°C~70°C TA. Using this switching controller, it is possible to switch at 500kHz. A generalization of dc dc regulator can be made using Surface Mount. To ensure efficient switching, this dcdc regulator features a Frequency Control. An analog IC with the SWITCHING CONTROLLER signal is connected to the switch converters. A switching converters's terminal (s) sits at the DUAL position. A variety of dc switching's functions can be performed on 8 terminations. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. DC switcher's voltage input is 15V. You can find other relevant dc to dc converter ics by searching "UC384*B". Pins number 8 of switching converter in total. Specially, switching converter corresponds to type Switching Regulator or Controllers. Test statistics indicate DC regulator outputs 13.4V voltage. A maximum voltage of 25V is accepted by the dc to dc regulator as an input voltage. In most cases, the dc dc regulator's output current is 12mA. This information should be noted when you begin working with the component. As a result of this, the maximum duty cycle of the voltage regulator dc to dc must remain 48 % during power-up and power-down. The Surface Mount makes DC switcher suitable for most applications and prototypes. Switching controller operates at 250kHz Hz. Continually operating at more than 500μA may cause malfunctions and damage to the component.
