UC2844BD1 Overview
In the 8-SOIC (0.154, 3.90mm Width) package, the switching controller meets most application requirements. For 1 outputs, the dc motor controller is appropriate. The pmic is packaged in Tube solid enclosure. There are Transistor Driver dc switching's output (s) that it can handle. The supply and operating voltage of the dc control are 10V~30V. Qualified to work in a -25°C~85°C TA dc switcher. Switching can be done at Up to 500kHz with this switching controller. As it has a Surface Mount value, it can be used for general dc dc regulator. Switching control is made easier with the dcdc regulator's Frequency Control. The switch converters are connected to a SWITCHING CONTROLLER analog IC. Thare switching converters has a terminal (s) at DUAL . 8 terminations with various dc switching's functions. To name a few of the control techniques these dc dc converter ics adapt, it includes PULSE WIDTH MODULATION. 15V nominal DC switcher's voltage input. In addition to "UC2844", there are other relevant dc to dc converter ics you can find. There are 8 pins on switching converter. There is a particular type of Switching Regulator or Controllers in switching converter. Test statistics indicate DC regulator outputs 5.05V voltage. The dc to dc regulator is limited to 30V input voltage. normally, the dc dc regulator's output current is 1A, which you should keep in mind when starting a project. Power-up and power-down reliability is ensured voltage regulator dc to dc by setting the maximum duty cycle to 50 %. In most applications and prototype designs, DC switcher is qualified as a Surface Mount. The max frequency of the pmic can reach 500kHz. There is a possibility of damage to the component if the switching voltage regulators current exceeds 17mA.
