LTC7851EUHH#TRPBF Overview
With its 58-WFQFN Exposed Pad package, the switching controller fits the needs of most applications. 4 outputs are supported by the dc motor controller. PMIC is packaged in a solid enclosure of Tape & Reel (TR). A total of PWM Signal dc switching's outputs can be handled by it. DC control operates at 3V~5.5V volts and has 3V~5.5V supply voltage. Work well in dc switchers with a -40°C~125°C TJ. The switching controller can be switched at 250kHz~3MHz. A generalization of dc dc regulator can be made using Surface Mount. Featured in the dcdc regulator is Current Limit, Enable, Frequency Control, Power Good, Soft Start, Tracking which allows efficient switching control. You can find other relevant dc to dc converter ics by searching "LTC7851". There are 58 pins on switching converter. It is set to 91.5 % duty cycle to ensure voltage regulator dc to dc reliability during power-ups and power-downs.
