UC3843AD8G4 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. There is a Tube solid enclosure around the pmic. 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 work in a 0°C~70°C TA dc switcher. Using this switching controller, it is possible to switch at Up to 500kHz. The Surface Mount value makes it suitable for general dc dc regulator. For efficient switching control, the dcdc regulator features Frequency Control. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. The switching converters's terminal (s) are designed at DUAL . A variety of 8 terminations are available in dc switching. PULSE WIDTH MODULATION is an example of one of the control techniques these dc dc converter ics adapt. DC switcher's input voltageis set to 15V. You can find other relevant dc to dc converter ics by searching "UC3843". Switching converter has a total of 8 pins. Switching converter is a special type of Switching Regulator or Controllers. Based on the test statistics, DC regulator outputs voltage 15V. The dc dc regulator's usual output current is 200mA, which should be noted down when you start a project. As a result of this, the maximum duty cycle of the voltage regulator dc to dc must remain 100 % during power-up and power-down. Switching controller operates at a frequency of 450kHz. For nominal working status, the input voltage can be set as 25V. Voltage 11V is required for supply. Current supplied to the controller should not exceed 25mA.
