LM2745MTCX Overview
With a 14-TSSOP (0.173, 4.40mm Width) package, the switching controller is suitable for a wide range of applications. PMIC packaging is solid with a Tape & Reel (TR) enclosure. Transistor Driver dc switching's outputs (s) can be handled by it. dc controls with 3V~6V voltage are supplied and operated. Qualified to work in an dc switcher with -40°C~125°C TJ. The switching controller can be switched at 50kHz~1MHz. The Surface Mount allows it to be used for dc dc regulator in general. Switching control is made easier with the dcdc regulator's Current Limit, Enable, Frequency Control, Power Good, Soft Start, Tracking. The switch converters are connected to a SWITCHING CONTROLLER analog IC. The switching converters's terminal (s) are designed at DUAL . A variety of dc switching's functions can be performed on 14 terminations. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. A DC switcher's nominal voltage of 3.3V is input. You can find other relevant dc to dc converter ics by searching "LM2745". Total pins of switching converter are 14. Specifically, switching converter falls under the Switching Regulator or Controllers category. Input voltage of dc dc voltage regulator must be 3V. Test statistics indicate DC regulator outputs 13.5V voltage. A maximum voltage of 6V is accepted by the dc to dc regulator as an input voltage. You should note down the dc dc regulator's usual output current of 20A when you start a project. Power-up and power-down reliability is ensured voltage regulator dc to dc by setting the maximum duty cycle to 86 %. In most applications and prototype designs, DC switcher is qualified as a Surface Mount. 1MHz is the maximum frequency of this dc regulators. When running the voltage regulator dc to dc in a circuit, users should apply 17V to ensure safety and reliability. A dc switching in a dormant state uses 1.7mA. During switching, this controller has a phase of 1.
