LM2748MTCX Overview
With its 14-TSSOP (0.173, 4.40mm Width) package, the switching controller fits the needs of most applications. An enclosure of Tape & Reel (TR) is used to package the PMIC. With Transistor Driver dc switching's output (s), it is able to handle it. This dc control operates at 3V~6V and has a 3V~6V supply voltage. Qualified to work in a -40°C~125°C TJ dc switcher. With this switching controller, you can switch at 50kHz~1MHz. The Surface Mount value makes it suitable for general dc dc regulator. To provide efficient switching control, Current Limit, Enable, Frequency Control, Power Good, Soft Start, Tracking is included in the dcdc regulator. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. Terminal (s) of the switching converters are designed at the DUAL position. A variety of terminations with 14 of dc switching. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. 3.3V nominal DC switcher's voltage input. You can find other relevant dc to dc converter ics by searching "LM2748". Switching converter has a total of 14 pins. There is a particular type of Switching Regulator or Controllers in switching converter. It is recommended to use 3V as the minimum input voltage of dc dc voltage regulator. Statistically, the DC regulator outputs 13.5V voltage. The dc to dc regulator is limited to 6V input voltage. You should note down the dc dc regulator's usual output current of 20A when you start a project. It is set to 86 % duty cycle to ensure voltage regulator dc to dc reliability during power-ups and power-downs. DC switcher's Surface Mount qualifies it for most applications and prototypes. There is a maximum frequency of 1MHz on this dc regulators. In order to run the voltage regulator dc to dc safely and reliably, users are advised to apply 17V. As long as the dc switching is in a dormant state, it utilizes 1.7mA. Phases of this controller are 1.
