UC3845AD8 Overview
Capsuled in the 8-SOIC (0.154, 3.90mm Width) package, the switching controller suits most application needs. For outputs of 1, this dc motor controller is suitable. Tube solid enclosure protects the pmic. Transistor Driver dc switching's outputs (s) can be handled by it. Voltages 7.6V~30V are the dc control's supply voltage and operating voltage, respectively. Suitable for a 0°C~70°C TA dc switcher. The Surface Mount allows it to be used for dc dc regulator in general. In order to control switching efficiently, the dcdc regulator features Frequency Control. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. The switching converters's terminals (s) are designed at DUAL. Various 8 terminations. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. A DC switcher's nominal voltage of 15V is input. Other relevant dc to dc converter ics will be returned if you search "UC3845". 8 pins are present on switching converter. In particular, switching converter belongs to the Switching Regulator or Controllers family. Statistically, DC regulator outputs 5V volts. If you start a project, note down the dc dc regulator's usual output current of 200mA. The duty cycle of the voltage regulator dc to dc can be set to 50 % on power-up or power-down to ensure reliability. A frequency of 500kHz is used by the switching controller. A dc switching in a dormant state uses 11mA. 15V is the nominal working voltage. This voltage controller requires a supply voltage of 11V. There should be 25mA more than 25mA amps of current supplied to the controller. The switching converter could be operated with an input of 11mA current flow.
