LM5642MTCX Product Details

LM5642MTCX Overview


Capsuled in the 28-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 2 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 4.5V~36V are the dc control's supply voltage and operating voltage, respectively. Work well in dc switchers with a -40°C~125°C TJ. Using this switching controller, it is possible to switch at 200kHz. A generalization of dc dc regulator can be made using Surface Mount. To ensure efficient switching, this dcdc regulator features a Current Limit, Enable, Soft Start. An analog IC with the DUAL 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 28 terminations. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. DC switcher's voltage input is 5V. You can find other relevant dc to dc converter ics by searching "LM5642". Pins number 28 of switching converter in total. An input voltage of 4.5V is the minimum required for the dc dc voltage regulator. Test statistics indicate DC regulator outputs 32.4V voltage. A maximum voltage of 36V is accepted by the dc to dc regulator as an input voltage. In most cases, the dc dc regulator's output current is 20A. This information should be noted when you begin working with the component. As a result of this, the maximum duty cycle of the voltage regulator dc to dc must remain 98.9 % during power-up and power-down. The Surface Mount makes DC switcher suitable for most applications and prototypes. It is estimated that this dc regulatorhas a maximum frequency of 226kHz. A dc switching in a dormant state uses 1.1mA.
