UC3845BD Overview
With its 14-SOIC (0.154, 3.90mm Width) package, the switching controller fits the needs of most applications. This dc motor controller can be used to generate outputs with 1 numbers. A solid enclosure of Tube surrounds pmic. The program can handle Transistor Driver dc switching's outputs (s). This dc control has a supply voltage and operating voltage of 7.6V~30V. Suitable for working in an dc switcher that has a 0°C~70°C TA. This switching controller can switch at 500kHz. The Surface Mount allows it to be used for dc dc regulator in general. For efficient switching control, the dcdc regulator features Frequency Control. An analog IC SWITCHING CONTROLLER is connected to the switch converters. There are a terminal (s) on the switching converters that are designed at DUAL. 14 terminations with various dc switching's functions. PULSE WIDTH MODULATION is an example of one of the control techniques these dc dc converter ics adapt. The DC switcher's nominal voltage is 15V. Search for "UC384*B" to find other relevant dc to dc converter ics. Switching converter has a total of 14 pins. In particular, switching converter belongs to the Switching Regulator or Controllers family. The test statistics indicate that DC regulator outputs a voltage of 5.1V. It should be fully noted that the dc to dc regulator only accepts 25V input voltage at most. You should note that the dc dc regulator's usual output current is 1A. The duty cycle of the voltage regulator dc to dc can be set to 48 % on power-up or power-down to ensure reliability. There is 275kHz frequency setting on the switching controller. To run the voltage regulator dc to dc safely and reliably, users should apply 30V to the voltage regulator dc to dc. In dormant mode, 12mA is used.
