UC2843ADTR Product Details

UC2843ADTR Overview


This switching controller fits most application requirements since it is packaged in a 14-SOIC (0.154, 3.90mm Width) package. 1 outputs are supported by the dc motor controller. Tape & Reel (TR) is the solid enclosure in which PMIC is packaged. It is capable of handling Transistor Driver dc switching's outputs (s). dc controls with 7.6V~30V voltage are supplied and operated. Suitable for working in an dc switcher that has a -40°C~85°C TA. Using this switching controller, it is possible to switch at Up to 500kHz. The Surface Mount makes it ideal for general dc dc regulator. In order to control switching efficiently, the dcdc regulator features Frequency Control. The switch converters are connected to a SWITCHING CONTROLLER analog IC. There are a DUAL terminal on the switching converters. The 14 terminations can be used for a wide range of dc switching. To name a few of the control techniques these dc dc converter ics adapt, it includes PULSE WIDTH MODULATION. DC switcher's input voltageis set to 15V. You can find other relevant dc to dc converter ics by searching "UC2843". 14 pins are present on switching converter. Switching converter type is specifically Switching Regulator or Controllers. A 15V voltage of DC regulator was detected in the test statistics. It's important to remember that the dc dc regulator's normaloutput current is 200mA, so you should note it down when starting a new project. Power-up and power-down reliability is ensured voltage regulator dc to dc by setting the maximum duty cycle to 100 %. Switching controller operates at a frequency of 450kHz. It is possible to set the input voltage as 25V for nominal working statuses. This voltage controller requires a supply voltage of 11V. Current supplied to the controller should not exceed 25mA.
