UC3879N Overview

In the 20-DIP (0.300, 7.62mm) package, the switching controller meets most application requirements. dc motor controller is suitable for 4 output generation. A solid enclosure of Tube surrounds pmic. It is capable of handling Transistor Driver dc switching's outputs (s). 9V~20V is the supply voltage and the operating voltage of the dc control. Worked in a 0°C~70°C TA dc switcher before. The switching controller can be switched at Up to 300kHz. It is suitable for general dc dc regulator when it is set to Through Hole. Switching control is made easier with the dcdc regulator's Frequency Control, Ramp, Soft Start. The switch converters are connected to a SWITCHING CONTROLLER analog IC. Switching converters are designed with the terminal (s) at position DUAL . A variety of terminations with 20 of dc switching. PULSE WIDTH MODULATION is an example of one of the control techniques these dc dc converter ics adapt. The DC switcher's nominal voltage is 12V. A search for "UC3879" will reveal other relevant dc to dc converter ics. The switching converter has a total of 20 pins. Switching converter is a special type of Switching Regulator or Controllers. DC regulator outputs 2.2V voltage according to the test statistics. It's important to remember that the dc dc regulator's normaloutput current is 2A, so you should note it down when starting a new project. Because of DC switcher's Through Hole, it is suitable for most prototype designs and applications. Switching controller operates at 300kHz Hz. DC to DC voltage regulator has a value of ALSO HAS CONTROL MODE OF IPK, ALSO HAS CONTROL TECHNIQUE OF RESONANT to better satisfy the need. 12V is the nominal working voltage.
