LM2742MTCX/NOPB Overview
It comes in a 14-TSSOP (0.173, 4.40mm Width) package, so switching controller can be used for most applications. 1 outputs can be generated with the dc motor controller. There is a Tape & Reel (TR) solid enclosure around the pmic. With Transistor Driver dc switching's output (s), it is able to handle it. dc control's supply and operating voltages are 4.5V~5.5V. Worked in a -40°C~125°C TJ dc switcher before. Using this switching controller, it is possible to switch at 50kHz~2MHz. As it has a Surface Mount value, it can be used for general dc dc regulator. The dcdc regulator features Current Limit, Enable, Frequency Control, Power Good, Soft Start for efficient switching control. The switch converters are connected to a SWITCHING CONTROLLER analog IC. Terminal (s) of the switching converters are designed at the DUAL position. 14 terminations with various dc switching's functions. 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. A search for "LM2742" will reveal other relevant dc to dc converter ics. There are only 14 pins on switching converter. Statistically, DC regulator outputs 600mV volts. If you start a project, note down the dc dc regulator's usual output current of 20A. Having a Surface Mount makes DC switcher suitable for most application and prototype designs. The max frequency of the pmic can reach 2MHz. During dormancy, the dc switching uses 1.5mA. Because the dc switcher's maximum input voltage is 16V users must limit the voltage accordingly. The dc switcher will not provide an output current greater than 20A.
