UC2845AD8TR Overview
The switching controller fits in the 8-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. An enclosure of Tape & Reel (TR) is used to package the PMIC. There are Transistor Driver dc switching's output (s) that it can handle. dc controls with 7.6V~30V voltage are supplied and operated. Qualified to work in a -40°C~85°C TA dc switcher. The switching controller is capable of switching at the 500kHz position. The Surface Mount allows it to be used for dc dc regulator in general. In order to control switching efficiently, the dcdc regulator features Frequency Control. An analog IC with the SWITCHING CONTROLLER signal is connected to the switch converters. There are a terminal (s) on the switching converters that are designed at DUAL. There are many different types of terminations for 8. 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 15V. You can find other relevant dc to dc converter ics by searching "UC2845". In total, switching converter has 8 pins. In particular, switching converter belongs to the Switching Regulator or Controllers family. Based on the test statistics, DC regulator outputs voltage 15V. If you start a project, note down the dc dc regulator's usual output current of 200mA. 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 %. A frequency of 450kHz is set for the switching controller. You can set the input voltage to 25V for nominal working status. Voltage 11V is required for supply. Current supplied to the controller should not exceed 25mA.
