Description
LTC3728LXCUH#PBF Overview
With a 32-WFQFN Exposed Pad package, the switching controller is suitable for a wide range of applications. For 2 outputs, the dc motor controller is appropriate. A solid enclosure of Tube surrounds pmic. Transistor Driver dc switching's outputs (s) can be handled by it. This dc control has a supply voltage and operating voltage of 4.5V~28V. Worked in an dc switcher with a 0°C~85°C TA rating. Switching can be done at 260kHz~550kHz with this switching controller. The Surface Mount value makes it suitable for general dc dc regulator. For efficient switching control, the dcdc regulator features Enable, Power Good, Soft Start. Search for "LTC3728" to find other relevant dc to dc converter ics. There are a total of 32 pins on switching converter. The test statistics indicate that DC regulator outputs a voltage of 7V. You should note that the dc dc regulator's usual output current is 25A. In most applications and prototypes, DC switcher's Surface Mount makes it suitable. DC regulator has a maximum frequency of 590kHz. Ideally, dc regulator should be kept at a temperature of 0°C or higher. The temperature should not exceed 85°C degrees Celsius. The dc switcher's maximum input voltage is 28V, so users must limit the voltage accordingly. The supplier dc dc controller package for this part would be 32-QFN (5x5). A voltage of 4.5V is required for the supply. There are 1 channels for high-quality communication.
