UC3843AD1 Product Details

UC3843AD1 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 7.6V~30V volts and has 7.6V~30V supply voltage. Suitable for working in an dc switcher that has a -40°C~150°C TJ. 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 "UC3843", there are other relevant dc to dc converter ics you can find. There are 8 pins on switching converter. Specifically, switching converter falls under the Switching Regulator or Controllers category. The dc to dc regulator can only accept 30V input voltage. 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. Because of DC switcher's Surface Mount, it is suitable for most prototype designs and applications. A frequency of 500kHz is set for the switching controller. In dormant mode, 12mA is used.
