LM2743MTCX Overview
It comes in a 14-TSSOP (0.173, 4.40mm Width) package, so switching controller can be used for most applications. Packaging for the pmic consists of Tape & Reel (TR) solid enclosures. Transistor Driver dc switching's outputs (s) are supported. A 3V~6V voltage is supplied to the dc control and used for operating it. Work well in dc switchers with a -40°C~125°C TJ. Using this switching controller, it is possible to switch at 50kHz~1MHz. Surface Mount makes it suitable for general dc dc regulator. To ensure efficient switching, this dcdc regulator features a Current Limit, Enable, Frequency Control, Power Good, Soft Start, Tracking. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. There are a terminal (s) on the switching converters that are designed at DUAL. 14 terminations with a variety of function. Some of the control techniques adapted by these dc dc converter ics include PULSE WIDTH MODULATION. There is a DC switcher's nominal voltage of 3.3V. LM2743 can be used to locate other relevant dc to dc converter ics. The switching converter has a total of 14 pins. Specially, switching converter corresponds to type Switching Regulator or Controllers. It is recommended to use 3V as the minimum input voltage of dc dc voltage regulator. Statistically, the DC regulator outputs 13.5V voltage. The dc to dc regulator can only accept 6V 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. It is set to 80 % duty cycle to ensure voltage regulator dc to dc reliability during power-ups and power-downs. This Surface Mount makes DC switcher suitable for most prototypes and applications. There is a maximum frequency of 1MHz on this dc regulators. When the dc switching is dormant, it uses 1.5mA. A dc switcher can only produce an output current of 20A. There are 1 phases in this controller.
