UC2843AQD Overview
Capsuled in the 14-SOIC (0.154, 3.90mm Width) package, the switching controller suits most application needs. This dc motor controller can be used to generate outputs with 1 numbers. Packaged in solid enclosures, this pmic has a Tube rating. Transistor Driver dc switching's outputs (s) are supported. DC control operates at 7.6V~30V volts and has 7.6V~30V supply voltage. Qualified to work in an dc switcher with -40°C~125°C TA. It can switch at Up to 500kHz. The Surface Mount value makes it suitable 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. Switching converters are designed with the terminal (s) at position DUAL . There are many different types of terminations for 14. Some of the control techniques adapted by these dc dc converter ics include PULSE WIDTH MODULATION. DC switcher's voltage input is 15V. A search for "UC2843" will reveal other relevant dc to dc converter ics. Pins number 14 of switching converter in total. There is a particular type of Switching Regulator or Controllers in switching converter. As determined by the test statistics, the output voltage of DC regulator is 15V. It should be fully noted that the dc to dc regulator only accepts 25V input voltage at most. You should note that the dc dc regulator's usual output current is 200mA. During power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set to 100 %. Switching controller operates at 500kHz Hz. A dc switching in a dormant state uses 11mA.
