UC3842ADG4 Overview


Capsuled in the 14-SOIC (0.154, 3.90mm Width) package, the switching controller suits most application needs. There is sufficient capacity to generate switching controller for outputs 1. Packaging for the pmic consists of Tube solid enclosures. It is capable of dealing with Transistor Driver dc switching's output (s). dc switching'sThis dc control has a supply voltage and operating voltage of 10V~30V. A 0°C~70°C TA dc switcher is not a problem. There is a switch at Up to 500kHz that can be used with this controller. The Surface Mount makes it ideal for general dc dc regulator. In order to control switching efficiently, the dcdc regulator features Frequency Control. Switch converters are connected to ICs with SWITCHING CONTROLLER analog outputs. A switching converters's terminal (s) sits at the DUAL position. A variety of 14 terminations are available in dc switching. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. A DC switcher's nominal voltage of 15V is input. Searching "UC3842" will return other relevant dc to dc converter ics. There are a total of 14 pins on switching converter. Switching converter is a special type of Switching Regulator or Controllers. As determined by the test statistics, the output voltage of DC regulator is 15V. You should note down the dc dc regulator's usual output current of 200mA when you start a project. To ensure the reliability under power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set as 100 %. A frequency of 450kHz is used by the switching controller. 25V is the nominal working voltage. Switching controller is necessary to provide a voltage of 11V. Current supplied to the controller should not exceed 25mA.
