LTC3728LEGN-1#PBF Overview
With a 28-SSOP (0.154, 3.90mm Width) package, the switching controller is suitable for a wide range of applications. There is sufficient capacity to generate switching controller for outputs 2. PMIC is packaged in a solid enclosure of Tube. Transistor Driver dc switching's outputs (s) can be handled by it. DC control operates at 4.5V~28V volts and has 4.5V~28V supply voltage. Suitable for a -40°C~85°C TA dc switcher. The switching controller can be switched at 260kHz~550kHz. dc dc regulator can be generalized using Surface Mount. DCDC regulator is controlled efficiently by Enable, Power Good, Soft Start. A DUAL SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. Switching converters are designed with the terminal (s) at position DUAL . Various 28 terminations. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. DC switcher's voltage input of 15V. Other relevant dc to dc converter ics can be found by searching "LTC3728". 28 pins are present on switching converter. Specifically, switching converter falls under the Switching Regulator or Controllers category. It is recommended that the dc dc voltage regulator's minimum input voltage be 4.5V. As determined by the test statistics, the output voltage of DC regulator is 3.35V. In most cases, the output current of the dc dc regulator will be 3A, so note that when you start the project. The Surface Mount makes DC switcher suitable for most applications and prototypes. 590kHz is the maximum frequency of this dc regulators. Communication with high quality requires 1 channels.
