LM3477AMM/NOPB Overview


In the 8-TSSOP, 8-MSOP (0.118, 3.00mm Width) package, the switching controller meets most application requirements. 1 outputs are supported by the dc motor controller. PMIC is packaged in a solid enclosure of Tape & Reel (TR). A total of Transistor Driver dc switching's outputs can be handled by it. A 2.97V~35V voltage is supplied to the dc control and used for operating it. Worked in an dc switcher with a -40°C~125°C TJ rating. Switching can be done at 500kHz with this switching controller. The Surface Mount allows it to be used for dc dc regulator in general. The dcdc regulator features Enable for efficient switching control. Connected to a SWITCHING CONTROLLER analog IC, the switch converters are connected to a power supply. Terminal (s) of the switching converters are designed at the DUAL position. Various 8 terminations. PULSE WIDTH MODULATION is an example of one of the control techniques these dc dc converter ics adapt. There is a DC switcher's nominal voltage of 12V. LM3477 can be searched for other relevant dc to dc converter ics. The switching converter has a total of 8 pins. An input voltage of 2.97V is the minimum required for the dc dc voltage regulator. Based on the test statistics, DC regulator outputs voltage 1.265V. Considering the dc to dc regulator can only accept 35V input voltage, it is important to take note of this. It's important to remember that the dc dc regulator's normaloutput current is 6A, so you should note it down when starting a new project. Power-up and power-down reliability is ensured voltage regulator dc to dc by setting the maximum duty cycle to 93 %. In most applications and prototype designs, DC switcher is qualified as a Surface Mount. It is estimated that this dc regulatorhas a maximum frequency of 575kHz. Dormant dc switchings use 2mA.
