UC3842AD Overview
As a result of 14-SOIC (0.154, 3.90mm Width) compact design, the switching controller is compatible with most applications. The dc motor controller is adquate to generate for 1 outputs. Tube is the solid enclosure in which PMIC is packaged. The system can process Transistor Driver dc switching's outputs (s). dc controls with 10V~30V voltage are supplied and operated. A 0°C~70°C TA dc switcher is not a problem. Using this switching controller, it is possible to switch at Up to 500kHz. dc dc regulator can be generalized using Surface Mount. In order to control switching efficiently, the dcdc regulator features Frequency Control. Switch converters are connected to ICs with SWITCHING CONTROLLER analog outputs. There are a DUAL terminal on the switching converters. A variety of terminations with 14 of dc switching. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. DC switcher's voltage input of 15V. You can find other relevant dc to dc converter ics by searching "UC3842". 14 pins are on switching converter. There is a particular type of Switching Regulator or Controllers in switching converter. DC regulator outputs 15V voltage based on test statistics. normally, the dc dc regulator's output current is 200mA, which you should keep in mind when starting a project. A duty cycle set at 100 % ensures voltage regulator dc to dc reliability during power-on and power-off. A frequency of 450kHz is used by the switching controller. You can set the input voltage to 25V for nominal working status. Voltage 11V must be supplied. There should be 25mA more than 25mA amps of current supplied to the controller. If the current flow input is 11mA, the switching converter could operate.
