UC3845BDR2 Overview


This switching controller fits most application requirements since it is packaged in a 14-SOIC (0.154, 3.90mm Width) package. For 1 outputs, the dc motor controller is appropriate. A solid enclosure of Tape & Reel (TR) surrounds pmic. There are Transistor Driver dc switching's output (s) that it can handle. 7.6V~30V is the supply voltage and the operating voltage of the dc control. Qualified to work in a 0°C~70°C TA dc switcher. The switching controller is capable of switching at the 500kHz position. The Surface Mount value makes it suitable for general dc dc regulator. To ensure efficient switching, this dcdc regulator features a 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. An array of 14 terminations of dc switching. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. DC switcher's input voltageis 15V volts. Search for "UC384*B" to find 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. As determined by the test statistics, the output voltage of DC regulator is 5.1V. Voltages 25V are the maximum that the dc to dc regulator will accept. You should note that the dc dc regulator's usual output current is 1A. During power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set to 48 %. DC regulators have a maximum frequency of 275kHz. When running the voltage regulator dc to dc in a circuit, users should apply 30V to ensure safety and reliability.
