LM3477AMMX/NOPB Overview


As a result of 8-TSSOP, 8-MSOP (0.118, 3.00mm Width) compact design, the switching controller is compatible with most applications. Packaged in solid enclosures, this pmic has a Tape & Reel (TR) rating. With Transistor Driver dc switching's output (s), it is able to handle it. 2.97V~35V is the supply voltage and the operating voltage of the dc control. Worked in a -40°C~125°C TJ dc switcher before. In this switching controller, the switch can be set to 500kHz. As it has a Surface Mount value, it can be used for general dc dc regulator. DCDC regulator is controlled efficiently by Enable. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. There are a terminal (s) on the switching converters that are designed at DUAL. 8 terminations with various dc switching's functions. This dc dc converter ic uses a variety of control techniques, including PULSE WIDTH MODULATION. DC switcher's input voltageis set to 12V. You can find other relevant dc to dc converter ics by searching "LM3477". There are 8 pins on switching converter. dc dc voltage regulators should have a minimum input voltage of 2.97V. Statistically, DC regulator outputs 1.265V volts. In most cases, the output current of the dc dc regulator will be 6A, so note that when you start the project. Voltage regulator dc to dc is designed to operate at 93 % duty cycle during power-ups and power-downs to ensure reliability. The Surface Mount makes DC switcher suitable for most applications and prototypes. DC regulator575kHz has the maximum frequency. For safe and reliable operation in a circuit, voltage regulator dc to dc is suggested that users apply 35V. During dormancy, the dc switching uses 2mA. Switching with 1 phases is the property of this controller.
