LM2745MTCX/NOPB Overview

It comes in a 14-TSSOP (0.173, 4.40mm Width) package, so switching controller can be used for most applications. The dc motor controller is adquate to generate for 1 outputs. Tape & Reel (TR) is the solid enclosure in which PMIC is packaged. There are Transistor Driver dc switching's output (s) that it can handle. dc control's supply and operating voltages are 3V~6V. Suitable for a -40°C~125°C TJ dc switcher. Using this switching controller, it is possible to switch at 50kHz~1MHz. As it has a Surface Mount value, it can be used for general dc dc regulator. Switching control is made easier with the dcdc regulator's Current Limit, Enable, Frequency Control, Power Good, Soft Start, Tracking. An analog IC SWITCHING CONTROLLER is connected to the switch converters. switching converters terminal (s) are designed to be at DUAL. An array of 14 terminations of dc switching. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. DC switcher's input voltageis set to 3.3V. A search for "LM2745" will reveal other relevant dc to dc converter ics. There are only 14 pins on switching converter. The minimum input voltage of the dc dc voltage regulator should be 3V. DC regulator outputs 13.5V voltage according to the test statistics. Considering the dc to dc regulator can only accept 6V input voltage, it is important to take note of this. In most cases, the output current of the dc dc regulator will be 20A, so note that when you start the project. As a result of this, the maximum duty cycle of the voltage regulator dc to dc must remain 86 % during power-up and power-down. Having a Surface Mount makes DC switcher ideal for most prototype and application designs. The max frequency of the pmic can reach 1MHz. In order for the voltage regulator dc to dc to perform safely and reliably in a circuit, users are advised to apply 17V. As long as the dc switching is in a dormant state, it utilizes 1.7mA.
