UC3845D8 Product Details
UC3845D8 Overview
Capsuled in the 8-SOIC (0.154, 3.90mm Width) package, the switching controller suits most application needs. There is sufficient capacity to generate switching controller for outputs 1. The pmic is packaged in Tube solid enclosure. With this function, you can deal with Transistor Driver dc switching's outputs (s). 12V~28V is the operating voltage and supply voltage of the dc control. Suitable for a 0°C~70°C TA dc switcher. With this switching controller, you can switch at 500kHz. It is suitable for general dc dc regulator when it is set to Surface Mount. DCDC regulator is controlled efficiently by Frequency Control. A SWITCHING CONTROLLER analog IC is connected to 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 used by these dc dc converter ics are PULSE WIDTH MODULATION. A DC switcher's nominal voltage of 15V is input. Other relevant dc to dc converter ics can be found by searching "UC3845". There are a total of 8 pins on switching converter. In particular, switching converter belongs to the Switching Regulator or Controllers family. According to the test statistics, DC regulator outputs 13.5V voltage. You should note down the dc dc regulator's usual output current of 1A 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 %. There is 450kHz frequency setting on the switching controller. As long as the dc switching is in a dormant state, it utilizes 11mA. You can set the input voltage to 25V for nominal working status. It is important that the controller is supplied with 25mA more than 25mA volts of current. If the current flow input is 11mA, the switching converter could operate.
