UC2843BD1R2 Overview
It comes in the 8-SOIC (0.154, 3.90mm Width) package, which makes switching controller suitable for most applications. For outputs of 1, this dc motor controller is suitable. PMIC packaging is solid with a Tape & Reel (TR) enclosure. There are Transistor Driver dc switching's output (s) that it can handle. The supply and operating voltage of the dc control are 7.6V~30V. Workable in an dc switcher where -25°C~85°C TA is the -25°C~85°C TArm. With this switching controller, you can switch at Up to 500kHz. A generalization of dc dc regulator can be made using Surface Mount. In order to control switching efficiently, the dcdc regulator features Frequency Control. The switch converters are connected to a SWITCHING CONTROLLER analog IC. A switching converters's terminal (s) sits at the DUAL position. A variety of 8 terminations are available in dc switching. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. DC switcher's input voltageis set to 15V. Other relevant dc to dc converter ics can be found by searching "UC284*B". Total pins of switching converter are 8. Particularly, switching converter is a type of Switching Regulator or Controllers. DC regulator outputs 5.05V voltage according to the test statistics. This dc to dc regulator accepts only 25V input voltage at most. If you are starting a new project, you should note the dc dc regulator's typical output current is 1A. The duty cycle of the voltage regulator dc to dc can be set to 96 % on power-up or power-down to ensure reliability. The switching controller works at a frequency of 60kHz. A circuit should contain 30V in order to ensure the voltage regulator dc to dc runs safely and reliably. Dormant dc switchings use 12mA.
