UC3845BVD1 Overview
In the 8-SOIC (0.154, 3.90mm Width) package, the switching controller meets most application requirements. 1 outputs can be generated with the dc motor controller. The pmic is packaged in Tube solid 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 -40°C~105°C TA. Using this switching controller, it is possible to switch at 500kHz. Surface Mount makes it suitable for general dc dc regulator. For efficient switching control, the dcdc regulator features Frequency Control. 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 terminations with 8 of dc switching. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. The DC switcher's nominal voltage is 15V. Other relevant dc to dc converter ics will be returned if you search "UC384*B". Switching converter has a total of 8 pins. There is a particular type of Switching Regulator or Controllers in switching converter. As determined by the test statistics, the output voltage of DC regulator is 5.1V. It should be noted that the dc to dc regulator only accepts 25V voltage as input voltage. You should note that the dc dc regulator's usual output current is 1A. A duty cycle set at 48 % ensures voltage regulator dc to dc reliability during power-on and power-off. DC regulator's maximum frequency is 275kHz. It is suggested that users apply 30V to the voltage regulator dc to dc in order to run it safely and reliably in a circuit.
