UC3842AD8 Product Details
UC3842AD8 Overview
As a result of 8-SOIC (0.154, 3.90mm Width) compact design, the switching controller is compatible with most applications. 1 outputs are supported by the dc motor controller. Tube is the solid enclosure in which PMIC is packaged. A total of Transistor Driver dc switching's outputs can be handled by it. Voltages 10V~30V are the dc control's supply voltage and operating voltage, respectively. Suitable for work in a 0°C~70°C TA dc switcher. A switching controller such as this can switch at a value of Up to 500kHz . The Surface Mount makes it ideal for general dc dc regulator. The dcdc regulator features Frequency Control for efficient switching control. SWITCHING CONTROLLER analog IC connects the switch converters. Switching converters are designed with the terminal (s) at position DUAL . The 8 terminations can be used for a wide range of dc switching. PULSE WIDTH MODULATION is an example of one of the control techniques these dc dc converter ics adapt. There is a DC switcher's nominal voltage of 15V. Other relevant dc to dc converter ics can be found by searching "UC3842". There are only 8 pins on switching converter. In particular, switching converter is a type of Switching Regulator or Controllers. DC regulator outputs 5V voltage according to the test statistics. You should note down the dc dc regulator's usual output current of 1A when you start a project. Voltage regulator dc to dc is designed to operate at 100 % duty cycle during power-ups and power-downs to ensure reliability. Switching controllers operate at 450kHz frequencies. A nominal working status is achieved when the input voltage is set to 15V. The maximum input voltage of the dc switcher is 25V, so users need to limit the voltage accordingly. Switching controller is necessary to provide a voltage of 11V. The dc switcher will not provide an output current greater than 1A. 25mA more than 25mA current should be supplied to the controller. If the current flow input is 11mA, the switching converter could operate.
