UC3842BD1R2 Overview
It comes in a 8-SOIC (0.154, 3.90mm Width) package, so switching controller can be used for most applications. dc motor controller is suitable for 1 output generation. PMIC is packaged in a solid enclosure of Tape & Reel (TR). The program can handle Transistor Driver dc switching's outputs (s). dc controls with 10V~30V voltage are supplied and operated. Worked in a 0°C~70°C TA dc switcher before. It can switch at Up to 500kHz. A generalization of dc dc regulator can be made using Surface Mount. Frequency Control provides dcdc regulator efficient switching control. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. The switching converters's terminals (s) are designed at DUAL. 8 terminations with a variety of function. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. A DC switcher's nominal voltage of 15V is input. Other relevant dc to dc converter ics can be found by searching "UC384*B". Total pins of switching converter are 8. Switching converter is a type of Switching Regulator or Controllers in particular. DC regulator outputs 5.1V voltage based on test statistics. The dc to dc regulator can only accept a maximum input voltage of 25V. If you are starting a new project, you should note the dc dc regulator's typical output current is 1A. During power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set to 96 %. This Surface Mount makes DC switcher suitable for most prototypes and applications. When running the voltage regulator dc to dc in a circuit, users should apply 30V to ensure safety and reliability.
