LTC3728LIUH#PBF Overview
This switching controller fits most application requirements since it is packaged in a 32-WFQFN Exposed Pad package. 2 outputs are supported by the dc motor controller. An enclosure of Tube is used to package the PMIC. With Transistor Driver dc switching's output (s), it is able to handle it. dc control's supply and operating voltages are 4.5V~28V. Suitable for a -40°C~85°C TA dc switcher. It can switch at 260kHz~550kHz. dc dc regulator is made easier with Surface Mount. To ensure efficient switching, this dcdc regulator features a Enable, Power Good, Soft Start. An analog IC with the DUAL SWITCHING CONTROLLER signal is connected to the switch converters. QUAD are the position of the terminal of the switching converters. Various 32 terminations. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. The nominal DC switcher's voltage input is 15V. Searching "LTC3728" will return other relevant dc to dc converter ics. Switching converter has a total of 32 pins. Switching converter type is specifically Switching Regulator or Controllers. Input voltage of dc dc voltage regulator must be 3.6V. The test statistics indicate that DC regulator outputs a voltage of 7V. Considering the dc to dc regulator can only accept 30V input voltage, it is important to take note of this. This Surface Mount makes DC switcher suitable for most prototypes and applications. This dc regulatorhas a max frequency of 590kHz. A maximum value of 3A is output for current. Communication on 1 channels is high-quality.
