UC3827N-1 Overview


With a 24-DIP (0.600, 15.24mm) package, the switching controller is suitable for a wide range of applications. It is sufficient to generate 3 outputs with this dc motor controller. There is a Tube solid enclosure around the pmic. It is capable of dealing with Transistor Driver dc switching's output (s). dc switching'sThis dc control has a supply voltage and operating voltage of 7.6V~20V. Suitable for work in a 0°C~70°C TA dc switcher. Switching can be done at 220kHz with this switching controller. The Through Hole allows it to be used for dc dc regulator in general. Switching control is made easier with the dcdc regulator's Frequency Control, Ramp, Soft Start. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. switching converters terminal (s) are designed to be at DUAL. A variety of dc switching's functions can be performed on 24 terminations. A few of the control techniques these dc dc converter ics adapt include PULSE WIDTH MODULATION. It is inputted with a DC switcher's voltage of 15V. In addition to "UC3827", there are other relevant dc to dc converter ics you can find. 24 pins are on switching converter. Switching converter is a type of Switching Regulator or Controllers in particular. Test statistics indicate DC regulator outputs 2.5V voltage. In most cases, the output current of the dc dc regulator will be 100mA, so note that when you start the project. A duty cycle set at 95 % ensures voltage regulator dc to dc reliability during power-on and power-off. The Through Hole makes DC switcher suitable for most applications and prototypes. There is 450kHz frequency setting on the switching controller. To better satisfy the need, DC to DC voltage regulator has a value of CAN ALSO WORK IN CURRENT MODE. It is possible to set the input voltage as 15V for nominal working statuses.
