8 Terminals 12V~28V 8-Pin UC3842 DC to DC converter IC SWITCHING CONTROLLER 1 Outputs Up to 500kHz Transistor Driver
UC3842D8 Overview
In the 8-SOIC (0.154, 3.90mm Width) package, the switching controller meets most application requirements. There is sufficient capacity to generate switching controller for outputs 1. There is a Tube solid enclosure around the pmic. With this function, you can deal with Transistor Driver dc switching's outputs (s). DC control operates at 12V~28V volts and has 12V~28V supply voltage. Suitable for working in an dc switcher that has a 0°C~70°C TA. It can switch at Up to 500kHz. As it has a Surface Mount value, it can be used for general dc dc regulator. To provide efficient switching control, Frequency Control is included in the dcdc regulator. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. DUAL are the position of the terminal of the switching converters. Various 8 terminations. This dc dc converter ic uses a variety of control techniques, including PULSE WIDTH MODULATION. There is a DC switcher's nominal voltage of 15V. In addition to "UC3842", there are other relevant dc to dc converter ics you can find. There are 8 pins on switching converter. DC regulator outputs 13.5V voltage based on test statistics. A starting point for a project is to note down the dc dc regulator's usual output current, which is 1A. Voltage regulator dc to dc is designed to operate at 100 % duty cycle during power-ups and power-downs to ensure reliability. A frequency of 450kHz is set for the switching controller. It is possible to set the input voltage as 25V for nominal working statuses. It is important that the controller is supplied with 25mA more than 25mA volts of current.
