UC2844ADM Overview


It comes in the 8-SOIC (0.154, 3.90mm Width) package, which makes switching controller suitable for most applications. For 1 outputs, the dc motor controller is appropriate. PMIC is packaged in a solid enclosure of Tube. There are Transistor Driver dc switching's output (s) that it can handle. Voltages 10V~30V are the dc control's supply voltage and operating voltage, respectively. Suitable for working in an dc switcher that has a -40°C~85°C TA. Switching can be done at Up to 500kHz with this switching controller. The Surface Mount allows it to be used for dc dc regulator in general. The dcdc regulator features Frequency Control for efficient switching control. Switch converters are connected to ICs with SWITCHING CONTROLLER analog outputs. Switching converters are designed with the terminal (s) at position DUAL . Various 8 terminations. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. The nominal DC switcher's voltage input is 15V. UC*84 can be searched for other relevant dc to dc converter ics. There are a total of 8 pins on switching converter. In particular, switching converter belongs to the Switching Regulator or Controllers family. According to the test statistics, DC regulator outputs 5V voltage. At most, the dc to dc regulator accepts 30V input voltage. In most cases, the dc dc regulator's output current is 1A. This information should be noted when you begin working with the component. A duty cycle set at 50 % ensures voltage regulator dc to dc reliability during power-on and power-off. Because of DC switcher's Surface Mount, it is suitable for most prototype designs and applications. There is 500kHz frequency setting on the switching controller. A dc switching in a dormant state uses 11mA. The supply current of the voltage controller is 11mA.
