LM2748MTC Overview


As a result of 14-TSSOP (0.173, 4.40mm Width) compact design, the switching controller is compatible with most applications. There is sufficient capacity to generate switching controller for outputs 1. Packaged in solid enclosures, this pmic has a Tube rating. There are Transistor Driver dc switching's output (s) that it can handle. dc controls with 3V~6V voltage are supplied and operated. Suitable for a -40°C~125°C TJ dc switcher. In this switching controller, the switch can be set to 50kHz~1MHz. As it has a Surface Mount value, it can be used for general dc dc regulator. To ensure efficient switching, this dcdc regulator features a Current Limit, Enable, Frequency Control, Power Good, Soft Start, Tracking. The switch converters are connected to a SWITCHING CONTROLLER analog IC. There are a terminal (s) on the switching converters that are designed at DUAL. 14 terminations with various dc switching's functions. A few of the control techniques these dc dc converter ics adapt include PULSE WIDTH MODULATION. There is a DC switcher's nominal voltage of 3.3V. You can find other relevant dc to dc converter ics by searching "LM2748". There are a total of 14 pins on switching converter. In particular, switching converter belongs to the Switching Regulator or Controllers family. Input voltage of dc dc voltage regulator must be 3V. Based on the test statistics, DC regulator outputs voltage 13.5V. The dc to dc regulator can only accept a maximum input voltage of 6V. If you start a project, note down the dc dc regulator's usual output current of 20A. To ensure the reliability under power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set as 86 %. As DC switcher has a Surface Mount, it's suitable for most applications and prototype designs. Switching controllers operate at 1MHz frequencies. To run the voltage regulator dc to dc safely and reliably, users should apply 17V to the voltage regulator dc to dc. A dc switching in a dormant state uses 1.7mA. The phase of this controller is 1.
