LM2647MTCX/NOPB Overview


Capsuled in the 28-TSSOP (0.173, 4.40mm Width) package, the switching controller can be used for a wide range of applications. 2 outputs are supported by the dc motor controller. 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. This dc control operates at 5.5V~28V and has a 5.5V~28V supply voltage. Worked in a -5°C~125°C TJ dc switcher before. Using this switching controller, it is possible to switch at 200kHz~500kHz. As it has a Surface Mount value, it can be used for general dc dc regulator. DCDC regulator is controlled efficiently by Current Limit, Enable, Frequency Control, Power Good, Soft Start. Thare switch converters are connected to an analog integrated circuit (IC) of type DUAL SWITCHING CONTROLLER. A switching converters's terminal (s) sits at the DUAL position. 28 terminations with various dc switching's functions. Some of the control techniques adapted by these dc dc converter ics include PULSE WIDTH MODULATION. The DC switcher's nominal voltage is 5V. LM2647 can be used to locate other relevant dc to dc converter ics. There are only 28 pins on switching converter. A 5V voltage of DC regulator was detected in the test statistics. 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 75 % during power-up and power-down. DC switcher's Surface Mount qualifies it for most applications and prototypes. This dc regulatorhas a max frequency of 500kHz. To run the voltage regulator dc to dc safely and reliably, users should apply 28V to the voltage regulator dc to dc. In dormant mode, 2.5mA is used.
