UC2843AQD8G4 Product Details

UC2843AQD8G4 Overview


It comes in a SOIC package, so switching controller can be used for most applications. This dc motor controller can be used to generate outputs with 1 numbers. A switching controller such as this can switch at a value of 500kHz . Switch converters are connected to ICs with SWITCHING CONTROLLER analog outputs. Thare switching converters has a terminal (s) at DUAL . 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 15V volts. The switching converter has a total of 8 pins. Switching converter is a special type of Switching Regulator or Controllers. As determined by the test statistics, the output voltage of DC regulator is 5V. The dc to dc regulator is limited to 25V input voltage. A duty cycle set at 100 % ensures voltage regulator dc to dc reliability during power-on and power-off. Keep dc regulator at a temperature of -40°C or above. Running the machine at 125°C is ideal. Switch converter has 1 total function(s). It is designed to have voltage regulators switchings with 8 pins. 500kHz is the maximum frequency at which the controller can switch. Ideally, it is suited for switching controllers with a 1kA input. According to its maximum supply voltage rating, the voltage controller is rated 30V. Tests are conducted at 5.05V to determine the dc controller's highest voltage output.
