LM25118MHE/NOPB Overview


It comes in the 20-PowerTSSOP (0.173, 4.40mm Width) package, which makes switching controller suitable for most applications. This dc motor controller can be used to generate outputs with 1 numbers. Tape & Reel (TR) solid enclosure protects the pmic. It is capable of dealing with Transistor Driver dc switching's output (s). dc switching'sA 3V~42V voltage is supplied to the dc control and used for operating it. A -40°C~125°C TJ dc switcher is not a problem. Using this switching controller, it is possible to switch at Up to 500kHz. The Surface Mount value makes it suitable for general dc dc regulator. Enable, Frequency Control, Ramp, Soft Start provides dcdc regulator efficient switching control. Thare switch converters are connected to an analog integrated circuit (IC) of type SWITCHING CONTROLLER. A switching converters's terminal (s) sits at the DUAL position. A variety of 20 terminations are available in dc switching. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. It is inputted with a DC switcher's voltage of 24V. Other relevant dc to dc converter ics will be returned if you search "LM25118". Switching converter has a total of 20 pins. In particular, switching converter belongs to the Switching Regulator or Controllers family. Statistically, DC regulator outputs 38V volts. In most cases, the output current of the dc dc regulator will be 3.5A, so note that when you start the project. It is set to 75 % duty cycle to ensure voltage regulator dc to dc reliability during power-ups and power-downs. As DC switcher has a Surface Mount, it's suitable for most applications and prototype designs. DC regulator's maximum frequency is 575kHz. A circuit should contain 14V in order to ensure the voltage regulator dc to dc runs safely and reliably. When the dc switching is dormant, it uses 4.5mA. Since the dc switcher's maximum input voltage is 42V, the voltage must be regulated accordingly. 3V is the required supply voltage. DC switchers cannot produce output currents greater than 4A. At its maximum output, the switching converter can provide 38V volts. A supply current of 4.5mA is used to power it. voltage controllers with a minimum voltage output of 1.23V cannot operate.
