    Products Detail

    L6997STR Overview


    Capsuled in the 20-TSSOP (0.173, 4.40mm Width) package, the switching controller can be used for a wide range of applications. There is enough capacity in the dc motor controller to generate the output for the 1 input. PMIC packaging is solid with a Tape & Reel (TR) enclosure. A total of Transistor Driver dc switching's outputs can be handled by it. Voltages 3V~5.5V are the dc control's supply voltage and operating voltage, respectively. Work well in dc switchers with a -40°C~125°C TJ. A generalization of dc dc regulator can be made using Surface Mount. To ensure efficient switching, this dcdc regulator features a Current Limit, Enable, Phase Control, Power Good, Soft Start. An analog IC with the SWITCHING CONTROLLER signal is connected to the switch converters. A switching converters's terminal (s) sits at the DUAL position. A variety of dc switching's functions can be performed on 20 terminations. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. DC switcher's voltage input is 3.3V. You can find other relevant dc to dc converter ics by searching "L6997". Pins number 20 of switching converter in total. Specially, switching converter corresponds to type Switching Regulator or Controllers. An input voltage of 3V is the minimum required for the dc dc voltage regulator. Test statistics indicate DC regulator outputs 12V voltage. A maximum voltage of 5.5V is accepted by the dc to dc regulator as an input voltage. In most cases, the dc dc regulator's output current is 30A. This information should be noted when you begin working with the component. The Surface Mount makes DC switcher suitable for most applications and prototypes. It is estimated that this dc regulatorhas a maximum frequency of 1MHz. Users should apply 35V to operate the voltage regulator dc to dc safely and reliably. A dc switching in a dormant state uses 600μA.
