LM3478QMMX/NOPB Product Details
LM3478QMMX/NOPB Overview
It comes in the 8-TSSOP, 8-MSOP (0.118, 3.00mm Width) package, which makes switching controller suitable for most applications. For 1 outputs, the dc motor controller is appropriate. A solid enclosure of Tape & Reel (TR) surrounds pmic. The system can process Transistor Driver dc switching's outputs (s). DC control operates at 2.97V~40V volts and has 2.97V~40V supply voltage. Suitable for a -40°C~125°C TJ dc switcher. There is a switch at 100kHz~1MHz that can be used with this controller. dc dc regulator is made easier with Surface Mount. The dcdc regulator features Enable, Frequency Control for efficient switching control. An analog IC SWITCHING CONTROLLER is connected to the switch converters. There are a DUAL terminal on the switching converters. A variety of 8 terminations are available in dc switching. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. The nominal DC switcher's voltage input is 12V. LM3478 can be searched for other relevant dc to dc converter ics. Switching converter has a total of 8 pins. In particular, switching converter is a type of Switching Regulator or Controllers. dc dc voltage regulators should have a minimum input voltage of 2.97V. Statistically, the DC regulator outputs 1.26V voltage. If you start a project, note down the dc dc regulator's usual output current of 1A. The maximum duty cycle of this voltage regulator dc to dc is set to 100 % to ensure reliability during power-up and power-down. This Surface Mount makes DC switcher suitable for most prototypes and applications. DC regulator's maximum frequency is 1MHz. For safe and reliable operation in a circuit, voltage regulator dc to dc is suggested that users apply 40V. There are several dc to dc voltage regulator in the Automotive, AEC-Q100 series. DC switching uses 2.7mA when it is dormant. Voltage 12V must be supplied.
