LTC3732CUHF#TRPBF Overview
This switching controller fits most application requirements since it is packaged in a 38-WFQFN Exposed Pad package. There is enough capacity in the dc motor controller to generate the output for the 3 input. An enclosure of Tape & Reel (TR) is used to package the PMIC. A total of Transistor Driver dc switching's outputs can be handled by it. A 4.5V~7V voltage is supplied to the dc control and used for operating it. Qualified to work in an dc switcher with 0°C~70°C TA. The switching controller can be switched at 225kHz~680kHz. The Surface Mount allows it to be used for dc dc regulator in general. To provide efficient switching control, Enable, Power Good, Soft Start is included in the dcdc regulator. A search for "LTC3732" will reveal other relevant dc to dc converter ics. The switching converter has a total of 38 pins. DC regulator's maximum frequency is 750kHz. At 0°C and above, dc regulator should be kept. There should be 70°C temperature above 70°C degrees Celsius when dc regulator runs. PolyPhase? is a series of dc to dc voltage regulator. A supplier dc dc controller package of 38-QFN (5x7) would be used for this part. Channels 1 are required for high-quality communication.
