E-UC2844BD1 Overview
With a 8-SOIC (0.154, 3.90mm Width) package, the switching controller is suitable for a wide range of applications. For 1 outputs, the dc motor controller is appropriate. Tube is the solid enclosure in which PMIC is packaged. With this function, you can deal with Transistor Driver dc switching's outputs (s). 10V~30V is the operating voltage and supply voltage of the dc control. Worked in a -25°C~85°C TA dc switcher before. There is a switch at Up to 500kHz that can be used with this controller. A generalization of dc dc regulator can be made using Surface Mount. DCDC regulator is controlled efficiently by Frequency Control. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. There are a terminal (s) on the switching converters that are designed at DUAL. An array of 8 terminations of dc switching. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. A DC switcher's nominal voltage of 15V is input. Searching "UC2844" will return other relevant dc to dc converter ics. Total pins of switching converter are 8. The test statistics indicate that DC regulator outputs a voltage of 5.05V. Voltages 30V are the maximum that the dc to dc regulator will accept. You should note down the dc dc regulator's usual output current of 1A when you start a project. The duty cycle of the voltage regulator dc to dc can be set to 50 % on power-up or power-down to ensure reliability. Having a Surface Mount makes DC switcher suitable for most application and prototype designs. There is 450kHz frequency setting on the switching controller.
