UC3843BDR2 Overview


Capsuled in the 14-SOIC (0.154, 3.90mm Width) package, the switching controller can be used for a wide range of applications. For 1 outputs, the dc motor controller is appropriate. PMIC is packaged in a solid enclosure of Tape & Reel (TR). Transistor Driver dc switching's outputs (s) are supported. Voltages 7.6V~30V are the dc control's supply voltage and operating voltage, respectively. Worked in an dc switcher with a 0°C~70°C TA rating. The switching controller can be switched at Up to 500kHz. The Surface Mount allows it to be used for dc dc regulator in general. Frequency Control provides dcdc regulator efficient switching control. The switch converters are connected to an analog IC with a SWITCHING CONTROLLER output. Switching converters are designed with the terminal (s) at position DUAL . The 14 terminations can be used for a wide range of dc switching. To name a few of the control techniques these dc dc converter ics adapt, it includes PULSE WIDTH MODULATION. DC switcher's input voltageis set to 15V. UC384*B can be searched for other relevant dc to dc converter ics. 14 pins are on switching converter. Particularly, 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. It should be noted that the dc to dc regulator only accepts 25V voltage as input voltage. The dc dc regulator's usual output current is 1A, which should be noted down when you start a project. During power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set to 96 %. Because of DC switcher's Surface Mount, it is suitable for most prototype designs and applications. DC regulator's maximum frequency is 275kHz.
