UC3845BVD Overview
With its 14-SOIC (0.154, 3.90mm Width) package, the switching controller fits the needs of most applications. dc motor controller is suitable for 1 output generation. A solid enclosure of Tube surrounds pmic. The system can process Transistor Driver dc switching's outputs (s). 7.6V~30V is the operating voltage and supply voltage of the dc control. Suitable for working in an dc switcher that has a -40°C~105°C TA. There is a switch at 500kHz that can be used with this controller. dc dc regulators can be carried out with Surface Mount. For efficient switching control, the dcdc regulator features Frequency Control. An analog IC SWITCHING CONTROLLER is connected to the switch converters. A switching converters's terminal (s) sits at the DUAL position. Various 14 terminations. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. 15V nominal DC switcher's voltage input. A search for "UC384*B" will reveal other relevant dc to dc converter ics. Total pins of switching converter are 14. In particular, switching converter is a type of Switching Regulator or Controllers. The test statistics indicate that DC regulator outputs a voltage of 5.1V. A maximum voltage of 25V is accepted by the dc to dc regulator as an input voltage. You should note that the dc dc regulator's usual output current is 1A. voltage regulator dc to dcs with a 48 % duty cycle are designed to be reliable when powered on and powered off. The Surface Mount makes DC switcher suitable for most applications and prototypes. Switching controllers work at 275kHz Hz. When running the voltage regulator dc to dc in a circuit, users should apply 30V to ensure safety and reliability. DC switching uses 12mA when it is dormant.
