UC3843NG4 Product Details
UC3843NG4 Overview
It comes in a 8-DIP (0.300, 7.62mm) package, so switching controller can be used for most applications. There is sufficient capacity to generate switching controller for outputs 1. An enclosure of Tube is used to package the PMIC. It is capable of handling Transistor Driver dc switching's outputs (s). 12V~28V is the operating voltage and supply voltage of the dc control. Suitable for a 0°C~70°C TA dc switcher. It can switch at Up to 500kHz. A generalization of dc dc regulator can be made using Through Hole. Switching control is made easier with the dcdc regulator's Frequency Control. An analog IC with the SWITCHING CONTROLLER signal is connected to the switch converters. switching converters terminal (s) are designed to be at DUAL. 8 terminations with a variety of function. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. 15V nominal DC switcher's voltage input. In addition to "UC3843", there are other relevant dc to dc converter ics you can find. 8 pins are present on switching converter. Switching converter is a special type of Switching Regulator or Controllers. Based on the test statistics, DC regulator outputs voltage 13.5V. You should note down the dc dc regulator's usual output current of 200mA when you start a project. Voltage regulator dc to dc is designed to operate at 100 % duty cycle during power-ups and power-downs to ensure reliability. Switching controller operates at 450kHz Hz. 25V is the nominal working voltage. The controller should not be supplied with more current than 25mA.
