LM3477MM/NOPB Overview
The switching controller fits in the 8-TSSOP, 8-MSOP (0.118, 3.00mm Width) package and is ideal for most applications. There is enough capacity in the dc motor controller to generate the output for the 1 input. There is a Tape & Reel (TR) solid enclosure around the pmic. A total of Transistor Driver dc switching's outputs can be handled by it. This dc control has a supply voltage and operating voltage of 2.97V~35V. A -40°C~125°C TJ dc switcher is not a problem. As it has a Surface Mount value, it can be used for general dc dc regulator. Enable provides dcdc regulator efficient switching control. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. The switching converters's terminal (s) are designed at DUAL . 8 terminations with various dc switching's functions. A few of the control techniques these dc dc converter ics adapt include PULSE WIDTH MODULATION. The nominal DC switcher's voltage input is 12V. Searching "LM3477" will return other relevant dc to dc converter ics. There are only 8 pins on switching converter. As determined by the test statistics, the output voltage of DC regulator is 1.265V. In most cases, the output current of the dc dc regulator will be 6A, so note that when you start the project. The duty cycle of the voltage regulator dc to dc can be set to 93 % on power-up or power-down to ensure reliability. Having a Surface Mount makes DC switcher ideal for most prototype and application designs. A frequency of 500kHz is used by the switching controller. The dc switching utilizes 2mA when it is in a dormant state. You can set the input voltage to 12V for nominal working status. The maximum input voltage of dc switcher is 35V, so users should limit their voltage accordingly. 2.97V is the required supply voltage. Output current will not exceed 1A. Datasheets indicate that the switching converter can output 2.5V volts at its maximum.
