UC2845BD1013TR Overview
As a result of 8-SOIC (0.154, 3.90mm Width) compact design, the switching controller is compatible with most applications. For 1 outputs, the dc motor controller is appropriate. Packaging for the pmic consists of Tape & Reel (TR) solid enclosures. The system can process Transistor Driver dc switching's outputs (s). A 7.6V~30V voltage is supplied to the dc control and used for operating it. Worked in an dc switcher with a -40°C~150°C TJ rating. In this switching controller, the switch can be set to 250kHz. The Surface Mount value makes it suitable for general dc dc regulator. To ensure efficient switching, this dcdc regulator features a Frequency Control. An analog IC with the SWITCHING CONTROLLER signal is connected to the switch converters. Thare switching converters has a terminal (s) at DUAL . A variety of dc switching's functions can be performed on 8 terminations. This dc dc converter ic uses a variety of control techniques, including PULSE WIDTH MODULATION. The nominal DC switcher's voltage input is 15V. A search for "UC2845" will reveal other relevant dc to dc converter ics. There are only 8 pins on switching converter. Specifically, switching converter falls under the Switching Regulator or Controllers category. Test statistics indicate DC regulator outputs 5V voltage. If you are starting a new project, you should note the dc dc regulator's typical output current is 1A. 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 %. Having a Surface Mount makes DC switcher suitable for most application and prototype designs. Switching controllers work at 500kHz Hz. DC switchings that are dormant use 12mA. You can set the input voltage to 15V for nominal working status. Components may be damaged if their current is greater than 17mA.
