LM2742MTCX Overview


The switching controller fits in the 14-TSSOP (0.173, 4.40mm Width) package and is ideal for most applications. The pmic is packaged in Tape & Reel (TR) solid enclosure. 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 4.5V~5.5V. Workable in an dc switcher where -40°C~125°C TJ is the -40°C~125°C TJrm. In this switching controller, the switch can be set to 50kHz~2MHz. The Surface Mount makes it ideal for general dc dc regulator. In order to control switching efficiently, the dcdc regulator features Current Limit, Enable, Frequency Control, Power Good, Soft Start. Connected to a SWITCHING CONTROLLER analog IC, the switch converters are connected to a power supply. There are a terminal (s) on the switching converters that are designed at DUAL. A variety of dc switching's functions can be performed on 14 terminations. A few of the control techniques these dc dc converter ics adapt include PULSE WIDTH MODULATION. The DC switcher's nominal voltage is 3.3V. You can find other relevant dc to dc converter ics by searching "LM2742". In total, switching converter has 14 pins. The type is a particular Switching Regulator or Controllers of switching converter. Test statistics indicate DC regulator outputs 13.5V voltage. The dc dc regulator's usual output current is 20A, which should be noted down when you start a project. Voltage regulator dc to dc is designed to operate at 90 % duty cycle during power-ups and power-downs to ensure reliability. 2MHz is the maximum frequency of this dc regulators. In a dormant state, the dc switching uses 1.5mA. Switching controller is necessary to have a supply voltage of 1V. The controller switches with phase number 1.
