E-UC3844BD1 Overview
It comes in the 8-SOIC (0.154, 3.90mm Width) package, which makes switching controller suitable for most applications. 1 outputs are supported by the dc motor controller. The pmic is packaged in Tube solid enclosure. There are Transistor Driver dc switching's output (s) that it can handle. The supply and operating voltage of the dc control are 10V~30V. Worked in an dc switcher with a 0°C~70°C TA rating. The switching controller can be switched at Up to 500kHz. dc dc regulator can be generalized using Surface Mount. In order to control switching efficiently, the dcdc regulator features Frequency Control. SWITCHING CONTROLLER analog IC connects the switch converters. Thare switching converters has a terminal (s) at DUAL . 8 terminations with various dc switching's functions. Some of the control techniques adapted by these dc dc converter ics include PULSE WIDTH MODULATION. There is a DC switcher's nominal voltage of 15V. Search for "UC3844" to find other relevant dc to dc converter ics. There are a total of 8 pins on switching converter. Based on the test statistics, DC regulator outputs voltage 5.1V. It should be noted that the dc to dc regulator only accepts 30V voltage as input voltage. In most cases, the output current of the dc dc regulator will be 1A, so note that when you start the project. voltage regulator dc to dcs with a 50 % duty cycle are designed to be reliable when powered on and powered off. The Surface Mount makes DC switcher suitable for most applications and prototypes. A frequency of 250kHz is set for the switching controller.
