LM3743MM-300/NOPB Overview


With its 10-TFSOP, 10-MSOP (0.118, 3.00mm Width) package, the switching controller fits the needs of most applications. It is sufficient to generate 1 outputs with this dc motor controller. PMIC is packaged in a solid enclosure of Tape & Reel (TR). The program can handle Transistor Driver dc switching's outputs (s). This dc control has a supply voltage and operating voltage of 3V~5.5V. Suitable for work in a -40°C~125°C TJ dc switcher. dc dc regulator can be generalized using Surface Mount. In order to control switching efficiently, the dcdc regulator features Current Limit, Enable, Soft Start, Tracking. An analog IC with the SWITCHING CONTROLLER signal is connected to the switch converters. DUAL are the position of the terminal of the switching converters. A variety of terminations with 10 of dc switching. These dc dc converter ics adapt a variety of control techniques, including PULSE WIDTH MODULATION. 3.3V nominal DC switcher's voltage input. You can find other relevant dc to dc converter ics by searching "LM3743". Pins number 10 of switching converter in total. The minimum input voltage of the dc dc voltage regulator should be 3V. Statistically, DC regulator outputs 4.6V volts. A starting point for a project is to note down the dc dc regulator's usual output current, which is 20A. Power-up and power-down reliability is ensured voltage regulator dc to dc by setting the maximum duty cycle to 91 %. Having a Surface Mount makes DC switcher suitable for most application and prototype designs. A frequency of 300kHz is set for the switching controller. DC to DC voltage regulator has a value of OUTPUT VOLTAGE ADJUSTABLE DOWN TO 0.8V to better satisfy the need. To run the voltage regulator dc to dc safely and reliably, users should apply 5V to the voltage regulator dc to dc. In a dormant state, the dc switching uses 1.8mA. The supply current of the voltage controller is 1.8mA. Phases of this controller are 1.
