LTC3728LXCUH#TRPBF Overview
With a 32-WFQFN Exposed Pad package, the switching controller is suitable for a wide range of applications. The dc motor controller is adquate to generate for 2 outputs. PMIC is packaged in a solid enclosure of Tape & Reel (TR). With Transistor Driver dc switching's output (s), it is able to handle it. 4.5V~28V is the operating voltage and supply voltage of the dc control. Suitable for working in an dc switcher that has a 0°C~85°C TA. It can switch at 260kHz~550kHz. The Surface Mount makes it ideal for general dc dc regulator. To ensure efficient switching, this dcdc regulator features a Enable, Power Good, Soft Start. Switch converters are connected to ICs with DUAL SWITCHING CONTROLLER analog outputs. The switching converters's terminal (s) are designed at QUAD . Different dc switching's functions can be applied to 32 terminations. These dc dc converter ics adapt a variety of control techniques, including PULSE WIDTH MODULATION. A DC switcher's nominal voltage of 15V is input. Searching "LTC3728" will return other relevant dc to dc converter ics. Total pins of switching converter are 32. Particularly, switching converter is a type of Switching Regulator or Controllers. It is recommended that the dc dc voltage regulator's minimum input voltage be 3.6V. As determined by the test statistics, the output voltage of DC regulator is 7V. It should be fully noted that the dc to dc regulator only accepts 30V input voltage at most. A starting point for a project is to note down the dc dc regulator's usual output current, which is 3A. The Surface Mount makes DC switcher suitable for most applications and prototypes. DC regulators have a maximum frequency of 590kHz. Communication on 1 channels is high-quality.
