UC3845D Overview
In the 14-SOIC (0.154, 3.90mm Width) package, the switching controller meets most application requirements. For 1 outputs, the dc motor controller is appropriate. The pmic is packaged in Tube solid enclosure. Transistor Driver dc switching's outputs (s) can be handled by it. dc controls with 7.6V~30V voltage are supplied and operated. Worked in a 0°C~70°C TA dc switcher before. A generalization of dc dc regulator can be made using Surface Mount. The switch converters are connected to an analog IC with a SWITCHING CONTROLLER output. Thare switching converters has a terminal (s) at DUAL . The 14 terminations can be used for a wide range of dc switching. These dc dc converter ics adapt a variety of control techniques, including PULSE WIDTH MODULATION. 15V nominal DC switcher's voltage input. Other relevant dc to dc converter ics will be returned if you search "UC3845". There are 14 pins on switching converter. Specifically, switching converter falls under the Switching Regulator or Controllers category. The minimum input voltage of the dc dc voltage regulator should be 8.2V. According to the test statistics, DC regulator outputs 5.1V voltage. Voltages 25V are the maximum that the dc to dc regulator will accept. The dc dc regulator's usual output current is 1A, which should be noted down when you start a project. Power-up and power-down reliability is ensured voltage regulator dc to dc by setting the maximum duty cycle to 50 %. Because of DC switcher's Surface Mount, it is suitable for most prototype designs and applications. DC regulator's maximum frequency is 500kHz.
