LM2747MTC Product Details

LM2747MTC Overview


It comes in a 14-TSSOP (0.173, 4.40mm Width) package, so switching controller can be used for most applications. An enclosure of Tube is used to package the PMIC. It is capable of dealing with Transistor Driver dc switching's output (s). dc switching'sThe supply and operating voltage of the dc control are 3V~6V. Workable in an dc switcher where -40°C~125°C TJ is the -40°C~125°C TJrm. With this switching controller, you can switch at 50kHz~1MHz. The Surface Mount allows it to be used for dc dc regulator in general. Current Limit, Enable, Frequency Control, Power Good, Soft Start, Tracking is used for efficient switching control in the dcdc regulator. A SWITCHING CONTROLLER analog IC is connected to the switch converters. Terminal (s) of the switching converters are designed at the DUAL position. An array of 14 terminations of dc switching. PULSE WIDTH MODULATION is an example of one of the control techniques these dc dc converter ics adapt. The DC switcher's nominal voltage is 3.3V. Other relevant dc to dc converter ics can be found by searching "LM2747". 14 pins are present on switching converter. Specifically, switching converter falls under the Switching Regulator or Controllers category. As determined by the test statistics, the output voltage of DC regulator is 13.5V. It's important to remember that the dc dc regulator's normaloutput current is 20A, so you should note it down when starting a new project. The duty cycle of the voltage regulator dc to dc can be set to 86 % on power-up or power-down to ensure reliability. Having a Surface Mount makes DC switcher ideal for most prototype and application designs. The max frequency of the pmic can reach 1MHz. To operate the voltage regulator dc to dc safely and reliably, users should apply 17V. Dormant dc switchings use 1.7mA. The maximum input voltage of dc switcher is 6V, so users should limit their voltage accordingly. In order to use a 3V voltage supply, switching controller is necessary to have one. There is 600mV voltage output lower than 600mV on the voltage controller. This controller contains 1 phases.
