UC2843ADR2 Overview


Capsuled in the 14-SOIC (0.154, 3.90mm Width) package, the switching controller suits most application needs. There is enough capacity in the dc motor controller to generate the output for the 1 input. An enclosure of Tape & Reel (TR) is used to package the PMIC. It is capable of dealing with Transistor Driver dc switching's output (s). dc switching's8.4V~30V is the supply voltage and the operating voltage of the dc control. Suitable for working in an dc switcher that has a -25°C~85°C TA. In this switching controller, the switch can be set to Up to 500kHz. It is suitable for general dc dc regulator when it is set to Surface Mount. Frequency Control provides dcdc regulator efficient switching control. An analog IC with the SWITCHING CONTROLLER signal is connected to the switch converters. There are a DUAL terminal on the switching converters. 14 terminations with various dc switching's functions. To name a few of the control techniques these dc dc converter ics adapt, it includes PULSE WIDTH MODULATION. 15V nominal DC switcher's voltage input. You can find other relevant dc to dc converter ics by searching "UC284*A". 14 pins are on switching converter. Specially, switching converter corresponds to type Switching Regulator or Controllers. dc dc voltage regulators should have a minimum input voltage of 8.2V. DC regulator outputs 5.05V voltage according to the test statistics. Switching controllers work at 60kHz Hz. A circuit should contain 30V in order to ensure the voltage regulator dc to dc runs safely and reliably. 1A is the largest value switching converter outputs. A dc switching in a dormant state uses 500μA.
