Description

UC3845ADTR Overview
It comes in the 14-SOIC (0.154, 3.90mm Width) package, which makes switching controller suitable for most applications. This dc motor controller can be used to generate outputs with 1 numbers. PMIC packaging is solid with a Tape & Reel (TR) enclosure. There are Transistor Driver dc switching's output (s) that it can handle. Voltages 7.6V~30V are the dc control's supply voltage and operating voltage, respectively. Qualified to work in an dc switcher with 0°C~70°C TA. In this switching controller, the switch can be set to 500kHz. As it has a Surface Mount value, it can be used for general dc dc regulator. Frequency Control is used for efficient switching control in the dcdc regulator. The switch converters are connected to a SWITCHING CONTROLLER analog IC. There are a terminal (s) on the switching converters that are designed at DUAL. A variety of 14 terminations are available in dc switching. This dc dc converter ic uses a variety of control techniques, including PULSE WIDTH MODULATION. There is a DC switcher's nominal voltage of 15V. You can find other relevant dc to dc converter ics by searching "UC3845". There are 14 pins on switching converter. In particular, switching converter is a type of Switching Regulator or Controllers. DC regulator outputs 15V voltage according to the 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. The maximum duty cycle of this voltage regulator dc to dc is set to 50 % to ensure reliability during power-up and power-down. 450kHz is the frequency of the switching controller. A nominal working status is achieved when the input voltage is set to 25V. A supply voltage of 11V is required. A controller's current should not exceed 25mA.
