UC2845AQD Overview


The switching controller fits in the 14-SOIC (0.154, 3.90mm Width) package and is ideal for most applications. There is enough capacity in the dc motor controller to generate the output for the 1 input. Packaging for the pmic consists of Tube solid enclosures. With this function, you can deal with Transistor Driver dc switching's outputs (s). This dc control has a supply voltage and operating voltage of 7.6V~30V. Worked in a -40°C~125°C TJ dc switcher before. Surface Mount makes it suitable for general dc dc regulator. Switching control is made easier with the dcdc regulator's Frequency Control. Thare switch converters are connected to an analog integrated circuit (IC) of type SWITCHING CONTROLLER. Terminal (s) of the switching converters are designed at the DUAL position. 14 terminations with various dc switching's functions. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. The nominal DC switcher's voltage input is 15V. Search for "UC2845" to find other relevant dc to dc converter ics. There are only 14 pins on switching converter. The type is a particular Switching Regulator or Controllers of switching converter. DC regulator outputs 15V voltage according to the test statistics. You should note down the dc dc regulator's usual output current of 200mA when you start a project. Power-up and power-down reliability is ensured voltage regulator dc to dc by setting the maximum duty cycle to 50 %. A frequency of 500kHz is used by the switching controller. DC switching uses 11mA when it is dormant. The maximum input voltage of dc switcher is 25V, so users should limit their voltage accordingly. Input current cannot exceed 1A with this dc switcher. 11mA current flow input could satisfy the switching converter for operation.
