UC3841N Product Details

UC3841N Overview


In the 18-DIP (0.300, 7.62mm) 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 8V~32V volts and has 8V~32V supply voltage. Suitable for working in an dc switcher that has a 0°C~70°C TA. It can switch at 500kHz. As it has a Through Hole value, it can be used for general dc dc regulator. To provide efficient switching control, Current Limit, Enable, Frequency Control, Ramp, Reset, Soft Start 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 18 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 20V. In addition to "UC3841", there are other relevant dc to dc converter ics you can find. There are 18 pins on switching converter. Specifically, switching converter falls under the Switching Regulator or Controllers category. DC regulator outputs 40V 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 400mA. Voltage regulator dc to dc is designed to operate at 95 % duty cycle during power-ups and power-downs to ensure reliability. A frequency of 450kHz is set for the switching controller. Hence, CURRENT MODE OPERATION IS ALSO POSSIBLE is used to better suit the DC to DC voltage regulator's situation. It is possible to set the input voltage as 30V for nominal working statuses. Input of 10mA current flow would satisfy the operation requirements of the switching converter .
