UC2845D8TR Overview
In the 8-SOIC (0.154, 3.90mm Width) package, the switching controller meets most application requirements. For 1 outputs, the dc motor controller is appropriate. There is a Tape & Reel (TR) solid enclosure around the pmic. It is capable of handling Transistor Driver dc switching's outputs (s). Voltages 12V~28V are the dc control's supply voltage and operating voltage, respectively. Suitable for work in a -40°C~85°C TA dc switcher. Switching can be done at 500kHz with this switching controller. dc dc regulator is made easier with Surface Mount. Frequency Control is used for efficient switching control in the dcdc regulator. An analog IC SWITCHING CONTROLLER is connected to the switch converters. The switching converters's terminal (s) are designed at DUAL . Various 8 terminations. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. DC switcher's voltage input is 15V. You can find other relevant dc to dc converter ics by searching "UC2845". There are only 8 pins on switching converter. The type is a particular Switching Regulator or Controllers of switching converter. DC regulator outputs 13.5V voltage according to the test statistics. It's important to remember that the dc dc regulator's normaloutput current is 200mA, so you should note it down when starting a new 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 %. Switching controllers operate at 450kHz frequencies. Input voltage can be set to 25V for nominal working status. A controller's current should not exceed 25mA.
