UC2843NG4 Overview
It comes in a 8-DIP (0.300, 7.62mm) package, so switching controller can be used for most applications. For 1 outputs, the dc motor controller is appropriate. PMIC packaging is solid with a Tube enclosure. With Transistor Driver dc switching's output (s), it is able to handle it. A 12V~28V voltage is supplied to the dc control and used for operating it. Qualified to work in a -40°C~85°C TA dc switcher. With this switching controller, you can switch at Up to 500kHz. The Through Hole makes it ideal for general dc dc regulator. To provide efficient switching control, Frequency Control is included in the dcdc regulator. The switch converters are connected to an analog IC with a SWITCHING CONTROLLER output. Thare switching converters has a terminal (s) at DUAL . 8 terminations with various dc switching's functions. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. 15V nominal DC switcher's voltage input. Searching "UC2843" will return other relevant dc to dc converter ics. 8 pins are on switching converter. Particularly, switching converter is a type of Switching Regulator or Controllers. Statistically, DC regulator outputs 13.5V volts. In most cases, the output current of the dc dc regulator will be 200mA, so note that when you start the project. It is set to 100 % duty cycle to ensure voltage regulator dc to dc reliability during power-ups and power-downs. Switching controller operates at a frequency of 450kHz. For nominal working status, the input voltage can be set as 25V. The maximum input voltage of this dc switcher is 25V, so users must limit the voltage accordingly. Input current cannot exceed 1A with this dc switcher. In order to ensure proper operation, the controller should not receive more current than 25mA. Input of 11mA current flow would satisfy the operation requirements of the switching converter .
