TL2844BD Overview
Capsuled in the 14-SOIC (0.154, 3.90mm Width) package, the switching controller can be used 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. There are Transistor Driver dc switching's output (s) that it can handle. 10V~30V is the operating voltage and supply voltage of the dc control. Worked in an dc switcher with a -40°C~85°C TA rating. There is a switch at Up to 500kHz that can be used with this controller. dc dc regulators can be carried out with Surface Mount. To ensure efficient switching, this dcdc regulator features a Frequency Control. Thare switch converters are connected to an analog integrated circuit (IC) of type SWITCHING CONTROLLER. Terminal (s) of the switching converters are designed at the DUAL position. Various 14 terminations. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. DC switcher's voltage input is 15V. TL2844 can be searched for other relevant dc to dc converter ics. Total pins of switching converter are 14. Specially, switching converter corresponds to type Switching Regulator or Controllers. Statistically, the DC regulator outputs 30V voltage. It's important to remember that the dc dc regulator's normaloutput current is 200mA, so you should note it down when starting a new project. It is set to 50 % duty cycle to ensure voltage regulator dc to dc reliability during power-ups and power-downs. 500kHz is the frequency of the switching controller. For nominal working status, the input voltage can be set as 5.5V.
