UC2845D8TRG4 Product Details

UC2845D8TRG4 Overview


With its 8-SOIC (0.154, 3.90mm Width) package, the switching controller fits the needs of most applications. This dc motor controller can be used to generate outputs with 1 numbers. A solid enclosure of Tape & Reel (TR) surrounds pmic. It is capable of dealing with Transistor Driver dc switching's output (s). dc switching's12V~28V is the supply voltage and the operating voltage of the dc control. Worked in a -40°C~85°C TA dc switcher before. Switching can be done at 500kHz with this switching controller. The Surface Mount value makes it suitable for general dc dc regulator. Frequency Control is used for efficient switching control in the dcdc regulator. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. switching converters terminal (s) are designed to be at DUAL. Various 8 terminations. This dc dc converter ic uses a variety of control techniques, including PULSE WIDTH MODULATION. There is a DC switcher's nominal voltage of 15V. UC2845 can be searched for 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. Based on the test statistics, DC regulator outputs voltage 13.5V. A starting point for a project is to note down the dc dc regulator's usual output current, which is 200mA. voltage regulator dc to dcs with a 50 % duty cycle are designed to be reliable when powered on and powered off. Switching controller operates at a frequency of 450kHz. For nominal working status, the input voltage can be set as 25V. The controller should not be supplied with more current than 25mA.
