LTC3728LIGN#PBF Product Details
LTC3728LIGN#PBF Overview
In the 28-SSOP (0.154, 3.90mm Width) package, the switching controller meets most application requirements. This dc motor controller can be used to generate outputs with 2 numbers. Tube is the solid enclosure in which PMIC is packaged. It is capable of handling Transistor Driver dc switching's outputs (s). This dc control has a supply voltage and operating voltage of 4.5V~28V. Suitable for working in an dc switcher that has a -40°C~85°C TA. This switching controller can switch at 260kHz~550kHz. As it has a Surface Mount value, it can be used for general dc dc regulator. DCDC regulator is controlled efficiently by Enable, Power Good, Soft Start. The switch converters are connected to a DUAL SWITCHING CONTROLLER analog IC. Switching converters are designed with the terminal (s) at position DUAL . 28 terminations with a variety of function. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. The DC switcher's nominal voltage is 15V. Search for "LTC3728" to find other relevant dc to dc converter ics. 28 pins are on switching converter. Specifically, switching converter falls under the Switching Regulator or Controllers category. It is recommended that the input voltage of the dc dc voltage regulator be 3.6V. Statistically, the DC regulator outputs 7V voltage. The dc to dc regulator can only accept a maximum input voltage of 30V. In most applications and prototype designs, DC switcher is qualified as a Surface Mount. DC regulator has a maximum frequency of 590kHz. A value of 3A is output as the maximum value of current. Communication with high quality requires 1 channels.
