UC2845BD1 Overview
As a result of 8-SOIC (0.154, 3.90mm Width) compact design, the switching controller is compatible with most applications. 1 outputs can be generated with the dc motor controller. Packaged in solid enclosures, this pmic has a Tube rating. It is capable of handling Transistor Driver dc switching's outputs (s). 7.6V~30V is the supply voltage and the operating voltage of the dc control. Suitable for work in a -40°C~150°C TJ dc switcher. The Surface Mount allows it to be used for dc dc regulator in general. Featured in the dcdc regulator is Frequency Control which allows efficient switching control. A SWITCHING CONTROLLER analog IC is connected to the switch converters. The switching converters's terminal (s) are designed at DUAL . A variety of dc switching's functions can be performed on 8 terminations. Some of the control techniques used by these dc dc converter ics are 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 "UC2845". The switching converter has a total of 8 pins. Switching converter type is specifically Switching Regulator or Controllers. According to the test statistics, DC regulator outputs 5.05V voltage. 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. A duty cycle set at 50 % ensures voltage regulator dc to dc reliability during power-on and power-off. Having a Surface Mount makes DC switcher ideal for most prototype and application designs. Switching controller operates at 250kHz Hz. For nominal working status, the input voltage can be set as 15V. The supply current of the voltage controller is 12mA.
