UC3843BVD1R2 Overview
Capsuled in the 8-SOIC (0.154, 3.90mm Width) package, the switching controller can be used for a wide range of applications. It is sufficient to generate 1 outputs with this dc motor controller. The pmic is packaged in Tape & Reel (TR) solid enclosure. The program can handle Transistor Driver dc switching's outputs (s). 7.6V~30V is the supply voltage and the operating voltage of the dc control. Qualified to work in a -40°C~105°C TA dc switcher. It can switch at Up to 500kHz. dc dc regulator is made easier with Surface Mount. Frequency Control provides dcdc regulator efficient switching control. An analog IC SWITCHING CONTROLLER is connected to the switch converters. Thare switching converters has a terminal (s) at DUAL . 8 terminations with various dc switching's functions. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. DC switcher's input voltageis 15V volts. Other relevant dc to dc converter ics can be found by searching "UC384*B". 8 pins are on switching converter. There is a particular type of Switching Regulator or Controllers in switching converter. According to the test statistics, DC regulator outputs 5.1V voltage. The dc to dc regulator can only accept a maximum input voltage of 25V. A starting point for a project is to note down the dc dc regulator's usual output current, which is 1A. It is set to 96 % duty cycle to ensure voltage regulator dc to dc reliability during power-ups and power-downs. Switching controllers work at 60kHz Hz. To run the voltage regulator dc to dc safely and reliably, users should apply 30V to the voltage regulator dc to dc. When the dc switching is dormant, it uses 12mA.
