UC3845DG4 Overview

As a result of 14-SOIC (0.154, 3.90mm Width) compact design, the switching controller is compatible with most applications. There is sufficient capacity to generate switching controller for outputs 1. The pmic is packaged in Tube solid enclosure. With Transistor Driver dc switching's output (s), it is able to handle it. A 12V~28V voltage is supplied to the dc control and used for operating it. Qualified to work in 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. Connected to a SWITCHING CONTROLLER analog IC, the switch converters are connected to a power supply. switching converters terminal (s) are designed to be at DUAL. Different dc switching's functions can be applied to 14 terminations. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. DC switcher's voltage input of 15V. Other relevant dc to dc converter ics will be returned if you search "UC3845". There are 14 pins on switching converter. Particularly, switching converter is a type of Switching Regulator or Controllers. DC regulator outputs 13.5V voltage according to the test statistics. You should note down the dc dc regulator's usual output current of 200mA when you start a project. Voltage regulator dc to dc is designed to operate at 50 % duty cycle during power-ups and power-downs to ensure reliability. There is 450kHz frequency setting on the switching controller. It is possible to set the input voltage as 25V for nominal working statuses. It is important that the controller is supplied with 25mA more than 25mA volts of current. If there is 11mA current flow input, then the switching converter could operate.
