LM2748MTCX/NOPB Overview
In the 14-TSSOP (0.173, 4.40mm Width) package, the switching controller meets most application requirements. PMIC is packaged in a solid enclosure of Tape & Reel (TR). Transistor Driver dc switching's outputs (s) can be handled by it. 3V~6V is the operating voltage and supply voltage of the dc control. Workable in an dc switcher where -40°C~125°C TJ is the -40°C~125°C TJrm. Using this switching controller, it is possible to switch at 50kHz~1MHz. dc dc regulator is made easier with Surface Mount. To ensure efficient switching, this dcdc regulator features a Current Limit, Enable, Frequency Control, Power Good, Soft Start, Tracking. An analog IC with the SWITCHING CONTROLLER signal is connected to the switch converters. Thare switching converters has a terminal (s) at DUAL . Different dc switching's functions can be applied to 14 terminations. PULSE WIDTH MODULATION is an example of one of the control techniques these dc dc converter ics adapt. The nominal DC switcher's voltage input is 3.3V. In addition to "LM2748", there are other relevant dc to dc converter ics you can find. The switching converter has a total of 14 pins. Input voltage of dc dc voltage regulator must 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. voltage regulator dc to dcs with a 86 % duty cycle are designed to be reliable when powered on and powered off. The Surface Mount makes DC switcher suitable for most applications and prototypes. 1MHz is the maximum frequency of this dc regulators. In order for the voltage regulator dc to dc to perform safely and reliably in a circuit, users are advised to apply 17V. A dc switching in a dormant state uses 1.7mA. Switches with 1 phases are used in this controller.
