UC3843BD1R2 Overview
Capsuled in the 8-SOIC (0.154, 3.90mm Width) package, the switching controller suits most application needs. dc motor controller is suitable for 1 output generation. PMIC packaging is solid with a Tape & Reel (TR) enclosure. The system can process Transistor Driver dc switching's outputs (s). dc control's supply and operating voltages are 7.6V~30V. Worked in an dc switcher with a 0°C~70°C TA rating. There is a switch at Up to 500kHz that can be used with this controller. dc dc regulator is made easier with Surface Mount. Frequency Control provides dcdc regulator efficient switching control. An analog IC SWITCHING CONTROLLER is connected to the switch converters. A switching converters's terminal (s) sits at the DUAL position. 8 terminations with various dc switching's functions. This dc dc converter ic uses a variety of control techniques, including PULSE WIDTH MODULATION. 15V nominal DC switcher's voltage input. You can find other relevant dc to dc converter ics by searching "UC384*B". There are 8 pins on switching converter. Switching converter is a special type of Switching Regulator or Controllers. A 5.1V voltage of DC regulator was detected in the test statistics. The dc to dc regulator is limited to 25V input voltage. In most cases, the dc dc regulator's output current is 1A. This information should be noted when you begin working with the component. During power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set to 96 %. Switching controller operates at 60kHz Hz. To run the voltage regulator dc to dc safely and reliably, users should apply 30V to the voltage regulator dc to dc. A dc switching in a dormant state uses 12mA.
