LM2743MTCX/NOPB Overview
This switching controller fits most application requirements since it is packaged in a 14-TSSOP (0.173, 4.40mm Width) package. 1 outputs are supported by the dc motor controller. PMIC packaging is solid with a Tape & Reel (TR) enclosure. With Transistor Driver dc switching's output (s), it is able to handle it. Voltages 3V~6V are the dc control's supply voltage and operating voltage, respectively. Suitable for work in a -40°C~125°C TJ dc switcher. This switching controller can switch at 50kHz~1MHz. dc dc regulator can be generalized using Surface Mount. DCDC regulator is controlled efficiently by Current Limit, Enable, Frequency Control, Power Good, Soft Start, Tracking. The switch converters are connected to a SWITCHING CONTROLLER analog IC. DUAL are the position of the terminal of the switching converters. Different dc switching's functions can be applied to 14 terminations. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. The DC switcher's nominal voltage is 3.3V. A search for "LM2743" will reveal other relevant dc to dc converter ics. There are a total of 14 pins on switching converter. The minimum input voltage of the dc dc voltage regulator should be 3V. Statistically, the DC regulator outputs 13.5V voltage. This dc to dc regulator accepts only 6V input voltage at most. A starting point for a project is to note down the dc dc regulator's usual output current, which is 20A. DC switcher's Surface Mount makes it qualified for most application and prototype designs. DC switcher'sThis dc regulatorhas a max frequency of 1MHz. During dormancy, the dc switching uses 1.5mA. There will be 20A output current greater than 20A from the dc switcher.
