UC3843BD1 Overview


It comes in the 8-SOIC (0.154, 3.90mm Width) package, which makes switching controller suitable for most applications. The dc motor controller is adquate to generate for 1 outputs. PMIC is packaged in a solid enclosure of Tube. Transistor Driver dc switching's outputs (s) can be handled by it. The supply and operating voltage of the dc control are 7.6V~30V. A 0°C~70°C TA dc switcher is not a problem. Switching can be done at Up to 500kHz with this switching controller. dc dc regulator is made easier with Surface Mount. The dcdc regulator features Frequency Control for efficient switching control. Connected to a SWITCHING CONTROLLER analog IC, the switch converters are connected to a power supply. There are a DUAL terminal on the switching converters. Various 8 terminations. These dc dc converter ics adapt a variety of control techniques, including PULSE WIDTH MODULATION. DC switcher's voltage input is 15V. A search for "UC384*B" will reveal other relevant dc to dc converter ics. 8 pins are present on switching converter. Switching converter type is specifically Switching Regulator or Controllers. As determined by the test statistics, the output voltage of DC regulator is 5.1V. You should note down the dc dc regulator's usual output current of 1A when you start a project. To ensure the reliability under power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set as 96 %. A frequency of 60kHz is used by the switching controller. If the user wishes to run the voltage regulator dc to dc in a circuit safely and reliably, they should apply 30V. The dc switching utilizes 12mA when it is in a dormant state.
