LTC3728LCUH#PBF Overview

In the 32-WFQFN Exposed Pad package, the switching controller meets most application requirements. For outputs of 2, this dc motor controller is suitable. Packaging for the pmic consists of Tube solid enclosures. There are Transistor Driver dc switching's output (s) that it can handle. The supply and operating voltage of the dc control are 4.5V~28V. A 0°C~85°C TA dc switcher is not a problem. Switching can be done at 260kHz~550kHz with this switching controller. Surface Mount makes it suitable for general dc dc regulator. Enable, Power Good, Soft Start provides dcdc regulator efficient switching control. An analog IC with the DUAL SWITCHING CONTROLLER signal is connected to the switch converters. The switching converters's terminals (s) are designed at QUAD. The 32 terminations can be used for a wide range of dc switching. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. DC switcher's input voltageis 15V volts. In addition to "LTC3728", there are other relevant dc to dc converter ics you can find. There are a total of 32 pins on switching converter. Particularly, switching converter is a type of Switching Regulator or Controllers. The test statistics indicate that DC regulator outputs a voltage of 5.5V. You should note that the dc dc regulator's usual output current is 3A. As a result of this, the maximum duty cycle of the voltage regulator dc to dc must remain 99.4 % during power-up and power-down. Because of DC switcher's Surface Mount, it is suitable for most prototype designs and applications. DC regulators have a maximum frequency of 590kHz. The dc switcher's maximum input voltage is 28V, so users must limit the voltage accordingly. Voltage 4.5V must be supplied. In order to ensure high-quality communication, there are 1 channels available.
