UC2844ADTR Product Details

UC2844ADTR Overview


With a 14-SOIC (0.154, 3.90mm Width) package, the switching controller is suitable for a wide range of applications. There is enough capacity in the dc motor controller to generate the output for the 1 input. There is a Tape & Reel (TR) solid enclosure around the pmic. With Transistor Driver dc switching's output (s), it is able to handle it. A 10V~30V voltage is supplied to the dc control and used for operating it. Worked in a -40°C~85°C TA dc switcher before. A switching controller such as this can switch at a value of Up to 500kHz . dc dc regulator can be generalized using Surface Mount. To ensure efficient switching, this dcdc regulator features a Frequency Control. SWITCHING CONTROLLER analog IC connects the switch converters. The switching converters's terminal (s) are designed at DUAL . A variety of 14 terminations are available in dc switching. 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. Searching "UC2844" will return other relevant dc to dc converter ics. 14 pins are present on switching converter. Specially, switching converter corresponds to type Switching Regulator or Controllers. DC regulator outputs 15V voltage according to the test statistics. If you are starting a new project, you should note the dc dc regulator's typical output current is 200mA. The duty cycle of the voltage regulator dc to dc can be set to 50 % on power-up or power-down to ensure reliability. DC switcher's Surface Mount makes it qualified for most application and prototype designs. DC switcher'sSwitching controller operates at 450kHz Hz. 25V is the nominal working voltage. This voltage controller requires a supply voltage of 11V. You should not supply more current than 25mA to the controller.
