UC3844BVD1R2 Overview
With a 8-SOIC (0.154, 3.90mm Width) package, the switching controller is suitable for a wide range of applications. The dc motor controller is adquate to generate for 1 outputs. Tape & Reel (TR) solid enclosure protects the pmic. A total of Transistor Driver dc switching's outputs can be handled by it. A 10V~36V voltage is supplied to the dc control and used for operating it. Suitable for a -40°C~105°C TA dc switcher. The switching controller is capable of switching at the Up to 500kHz position. dc dc regulator can be generalized using Surface Mount. To ensure efficient switching, this dcdc regulator features a Frequency Control. Switch converters are connected to ICs with SWITCHING CONTROLLER analog outputs. The switching converters's terminal (s) are designed at DUAL . 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. DC switcher's input voltageis 15V volts. In addition to "UC384*B", there are other relevant dc to dc converter ics you can find. There are only 8 pins on switching converter. There is a particular type of Switching Regulator or Controllers in switching converter. As determined by the test statistics, the output voltage of DC regulator is 5.1V. The dc to dc regulator is limited to 25V input voltage. The dc dc regulator's usual output current is 1A, which should be noted down when you start a project. It is set to 48 % duty cycle to ensure voltage regulator dc to dc reliability during power-ups and power-downs. 275kHz is the frequency of the switching controller. In order to run the voltage regulator dc to dc safely and reliably, users are advised to apply 30V. Dormant dc switchings use 12mA.
