UC3845ADG4 Overview

Capsuled in the 14-SOIC (0.154, 3.90mm Width) package, the switching controller suits most application needs. For 1 outputs, the dc motor controller is appropriate. Tube is the solid enclosure in which PMIC is packaged. There are Transistor Driver dc switching's output (s) that it can handle. This dc control operates at 7.6V~30V and has a 7.6V~30V supply voltage. Worked in a 0°C~70°C TA dc switcher before. As it has a Surface Mount value, it can be used for general dc dc regulator. To ensure efficient switching, this dcdc regulator features a Frequency Control. Switch converters are connected to ICs with SWITCHING CONTROLLER analog outputs. Terminal (s) of the switching converters are designed at the DUAL position. A variety of dc switching's functions can be performed on 14 terminations. Some of the control techniques adapted by these dc dc converter ics include PULSE WIDTH MODULATION. A DC switcher's nominal voltage of 15V is input. UC3845 can be searched for other relevant dc to dc converter ics. There are only 14 pins on switching converter. In particular, switching converter belongs to the Switching Regulator or Controllers family. DC regulator outputs 5.1V voltage based on test statistics. It's important to remember that the dc dc regulator's normaloutput current is 200mA, so you should note it down when starting a new project. Power-up and power-down reliability is ensured voltage regulator dc to dc by setting the maximum duty cycle to 50 %. A frequency of 500kHz is set for the switching controller. You can set the input voltage to 25V for nominal working status. Because the dc switcher's maximum input voltage is 25V users must limit the voltage accordingly. This voltage controller requires a supply voltage of 11V. A dc switcher can only produce an output current of 1A. There should be 25mA more than 25mA amps of current supplied to the controller. 11mA current flow input could be used to operate the switching converter .
