LM3477AMM Overview


In the 8-TSSOP, 8-MSOP (0.118, 3.00mm Width) package, the switching controller meets most application requirements. This dc motor controller can be used to generate outputs with 1 numbers. An enclosure of Tape & Reel (TR) is used to package the PMIC. The program can handle Transistor Driver dc switching's outputs (s). This dc control operates at 2.97V~35V and has a 2.97V~35V supply voltage. Suitable for work in a -40°C~125°C TJ dc switcher. The Surface Mount value makes it suitable for general dc dc regulator. DCDC regulator is controlled efficiently by Enable. An analog IC with the SWITCHING CONTROLLER signal is connected to the switch converters. Terminal (s) of the switching converters are designed at the DUAL position. An array of 8 terminations of dc switching. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. DC switcher's input voltageis set to 12V. LM3477 can be used to locate other relevant dc to dc converter ics. 8 pins are on switching converter. The type is a particular Switching Regulator or Controllers of switching converter. Test statistics indicate DC regulator outputs 1.265V voltage. You should note that the dc dc regulator's usual output current is 200mA. A duty cycle set at 93 % ensures voltage regulator dc to dc reliability during power-on and power-off. In most applications and prototypes, DC switcher's Surface Mount makes it suitable. Switching controller operates at 500kHz Hz. The dc switching utilizes 2mA when it is in a dormant state. It is possible to set the input voltage as 12V for nominal working statuses. The dc switcher's maximum input voltage is 35V; users must limit it accordingly. A voltage of 2.97V is required for the supply. There will be 1A output current greater than 1A from the dc switcher. If there is 2mA current flow input, then the switching converter could operate.
