UC3845BVD1R2 Overview
With its 8-SOIC (0.154, 3.90mm Width) package, the switching controller fits the needs of most applications. It is sufficient to generate 1 outputs with this dc motor controller. An enclosure of Tape & Reel (TR) is used to package the PMIC. With this function, you can deal with Transistor Driver dc switching's outputs (s). The supply and operating voltage of the dc control are 7.6V~30V. Qualified to work in a -40°C~105°C TA dc switcher. In this switching controller, the switch can be set to 500kHz. dc dc regulators can be carried out with Surface Mount. Switching control is made easier with the dcdc regulator's Frequency Control. Switch converters are connected to ICs with SWITCHING CONTROLLER analog outputs. A switching converters's terminal (s) sits at the DUAL position. The 8 terminations can be used for a wide range of dc switching. This dc dc converter ic uses a variety of control techniques, including 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 "UC384*B". The switching converter has a total of 8 pins. Particularly, switching converter is a type of Switching Regulator or Controllers. DC regulator outputs 5.1V voltage according to the test statistics. The dc to dc regulator can only accept a maximum input voltage of 25V. It's important to remember that the dc dc regulator's normaloutput current is 1A, so you should note it down when starting a new project. A duty cycle set at 48 % ensures voltage regulator dc to dc reliability during power-on and power-off. A frequency of 275kHz is set for the switching controller. In order for the voltage regulator dc to dc to perform safely and reliably in a circuit, users are advised to apply 30V. As long as the dc switching is in a dormant state, it utilizes 12mA.
