UC3856QG3 Overview
It comes in the 20-LCC (J-Lead) package, which makes switching controller suitable for most applications. 2 outputs can be generated with the dc motor controller. PMIC is packaged in a solid enclosure of Tube. With Transistor Driver dc switching's output (s), it is able to handle it. A 7V~40V voltage is supplied to the dc control and used for operating it. Workable in an dc switcher where 0°C~70°C TA is the 0°C~70°C TArm. In this switching controller, the switch can be set to 200kHz. The Surface Mount allows it to be used for dc dc regulator in general. Enable, Frequency Control, Soft Start provides dcdc regulator efficient switching control. The switch converters are connected to a SWITCHING CONTROLLER analog IC. Terminal (s) of the switching converters are designed at the QUAD position. A variety of dc switching's functions can be performed on 20 terminations. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. There is a DC switcher's nominal voltage of 15V. Searching "UC3856" will return other relevant dc to dc converter ics. There are only 20 pins on switching converter. In particular, switching converter belongs to the Switching Regulator or Controllers family. Statistically, the DC regulator outputs 13.1V voltage. You should note down the dc dc regulator's usual output current of 200mA when you start a project. To ensure the reliability under power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set as 50 %. 1MHz is the frequency of the switching controller. It is possible to set the input voltage to 40V for nominal working status.
