UC3843AD8TR Overview
It comes in the 8-SOIC (0.154, 3.90mm Width) package, which makes switching controller suitable for most applications. There is sufficient capacity to generate switching controller for outputs 1. Packaged in solid enclosures, this pmic has a Tape & Reel (TR) rating. Transistor Driver dc switching's outputs (s) are supported. This dc control operates at 7.6V~30V and has a 7.6V~30V supply voltage. Suitable for working in an dc switcher that has a 0°C~70°C TA. A switching controller such as this can switch at a value of Up to 500kHz . dc dc regulator can be generalized using Surface Mount. To ensure efficient switching, this dcdc regulator features a Frequency Control. Connected to a SWITCHING CONTROLLER analog IC, the switch converters are connected to a power supply. Switching converters are designed with the terminal (s) at position DUAL . Different dc switching's functions can be applied to 8 terminations. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. 15V nominal DC switcher's voltage input. UC3843 can be used to locate other relevant dc to dc converter ics. In total, switching converter has 8 pins. Switching converter is a special type of Switching Regulator or Controllers. Test statistics indicate DC regulator outputs 15V voltage. In most cases, the dc dc regulator's output current is 1A. This information should be noted when you begin working with the component. voltage regulator dc to dcs with a 100 % duty cycle are designed to be reliable when powered on and powered off. The switching controller works at a frequency of 500kHz. 25V is the nominal working voltage. A supply voltage of 11V is required. 25mA more than 25mA current should be supplied to the controller.
