LM27402SQ/NOPB Overview
It comes in a 16-WQFN Exposed Pad package, so switching controller can be used for most applications. For 1 outputs, the dc motor controller is appropriate. 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. This dc control operates at 3V~20V and has a 3V~20V supply voltage. Worked in an dc switcher with a -40°C~125°C TJ rating. It can switch at 200kHz~1.2MHz. As it has a Surface Mount value, it can be used for general dc dc regulator. Featured in the dcdc regulator is Current Limit, Enable, Frequency Control, Power Good, Soft Start, Tracking which allows efficient switching control. The switch converters are connected to an analog IC with a SWITCHING CONTROLLER output. switching converters terminal (s) are designed to be at QUAD. Different dc switching's functions can be applied to 16 terminations. This dc dc converter ic uses a variety of control techniques, including PULSE WIDTH MODULATION. It is inputted with a DC switcher's voltage of 12V. Search for "LM27402" to find other relevant dc to dc converter ics. Switching converter has a total of 16 pins. Test statistics indicate DC regulator outputs 18.6V voltage. It's important to remember that the dc dc regulator's normaloutput current is 30A, so you should note it down when starting a new project. The duty cycle of the voltage regulator dc to dc can be set to 95 % on power-up or power-down to ensure reliability. DC switcher's Surface Mount makes it qualified for most application and prototype designs. DC switcher'sDC regulator has a maximum frequency of 1.35MHz. DC switching uses 4.5mA when it is dormant. The maximum input voltage of the dc switcher is 20V, so users need to limit the voltage accordingly. The supply voltage must be 3V. The dc switcher will not provide an output current greater than 30A.
