LTC3890EGN-3#TRPBF is an advanced high-efficiency synchronous buck DC/DC controller device containing digital PWM control, designed to deliver the many advantages of switching regulator technology and customers\' need for higher efficiency, small size and low-cost. It also integrates SystemManagerTM technology, which allows both the PMOS and NMOS of the synchronous buck switch to be housed in a single device. LTC3890EGN-3#TRPBF is widely used in the following applications: digital applications such as microprocessor, telecom and laptop or notebook power systems, industrial power systems and automotive applications.

In terms of its working principle, the LTC3890EGN-3#TRPBF works in the same way as a typical synchronous buck regulator. When input voltage comes in, the device starts up as a non-synchronous buck regulator, allowing the buck transistor to turn on and off the current passing through the inductor at a fixed duty cycle. During the on time, current passing through the inductor rises until it reaches the programmed inductor peak current value. Afterward, the device acts as a synchronous buck regulator, allowing the buck transistor to turn on and off both the current and voltage at the same fixed duty cycle.

Moreover, LTC3890EGN-3#TRPBF has several highlights. One of them is its ability to monitor the output voltage and control the frequency of the switching in accordance with the output voltage, this eliminates the need for an external clock. In addition, over-current and other protection features are monitored and react in real time, reducing power dissipation. Furthermore, LTC3890EGN-3#TRPBF is capable of operating at wide range of frequencies up to 2MHz. Finally, it also has integrated low output voltage tracking, soft start and an internal SoftStart/SoftStop mode, enabling smooth transitions from one operating state to another.

In conclusion, LTC3890EGN-3#TRPBF is an advanced and high-efficiency synchronous buck DC/DC controller device. It contains digital PWM control technology and is widely used in digital and industrial applications, such as microprocessor, telecom, laptop and notebook power systems, industrial power systems and automotive applications. Its various highlights allow it to run at a wide range of frequencies up to 2MHz, as well as offer higher efficiency, small size and low-cost. Additionally, it also provides a variety of protection features for proper operation.
