UC3844BD1 Product Details
UC3844BD1 Overview
Capsuled in the 8-SOIC (0.154, 3.90mm Width) package, the switching controller can be used for a wide range of applications. For outputs of 1, this dc motor controller is suitable. PMIC packaging is solid with a Tube enclosure. There are Transistor Driver dc switching's output (s) that it can handle. This dc control operates at 10V~30V and has a 10V~30V supply voltage. Suitable for a 0°C~70°C TJ dc switcher. With this switching controller, you can switch at Up to 500kHz. It is suitable for general dc dc regulator when it is set to Surface Mount. Featured in the dcdc regulator is Frequency Control which allows efficient switching control. SWITCHING CONTROLLER analog IC connects the switch converters. A switching converters's terminal (s) sits at the DUAL position. The 8 terminations can be used for a wide range of dc switching. This dc dc converter ic uses a variety of control techniques, including PULSE WIDTH MODULATION. DC switcher's voltage input is 15V. UC3844 can be used to locate other relevant dc to dc converter ics. 8 pins are on switching converter. There is a particular type of Switching Regulator or Controllers in switching converter. Test statistics indicate DC regulator outputs 5.1V voltage. In most cases, the output current of the dc dc regulator will be 1A, so note that when you start the project. A duty cycle set at 50 % ensures voltage regulator dc to dc reliability during power-on and power-off. This Surface Mount makes DC switcher suitable for most prototypes and applications. A frequency of 500kHz is set for the switching controller. It is possible to set the input voltage to 30V for nominal working status. If the current exceeds 30mA, the component may not operate correctly and may even be damaged.
