UC2846Q Overview


With its 20-LCC (J-Lead) package, the switching controller fits the needs of most applications. The dc motor controller is adquate to generate for 2 outputs. PMIC packaging is solid with a Tube enclosure. With this function, you can deal with Transistor Driver dc switching's outputs (s). dc control's supply and operating voltages are 6.95V~40V. Worked in a -40°C~85°C TA dc switcher before. A switching controller such as this can switch at a value of 500kHz . The Surface Mount allows it to be used for dc dc regulator in general. To ensure efficient switching, this dcdc regulator features a Current Limit, Enable, Frequency Control, Soft Start. An analog IC SWITCHING CONTROLLER is connected to the switch converters. QUAD are the position of the terminal of the switching converters. There are many different types of terminations for 20. To name a few of the control techniques these dc dc converter ics adapt, it includes PULSE WIDTH MODULATION. DC switcher's voltage input is 15V. Searching "UC2846" will return other relevant dc to dc converter ics. There are a total of 20 pins on switching converter. Switching converter is a type of Switching Regulator or Controllers in particular. DC regulator outputs 13.5V voltage according to the test statistics. In most cases, the output current of the dc dc regulator will be 500mA, so note that when you start the project. Voltage regulator dc to dc is designed to operate at 50 % duty cycle during power-ups and power-downs to ensure reliability. DC switcher's Surface Mount qualifies it for most applications and prototypes. A frequency of 450kHz is set for the switching controller. It is possible to set the input voltage to 15V for nominal working status.
