The LTC4355CDE#TRPBF is a high-performance power management integrated circuit (PMIC) which combines the controller, ideal diode, and driver functions into one single small package. It is designed to provide a comprehensive solution to power system designers requiring an easy-to-use controller, ideal diode, and driver solution.

Application Field

The LTC4355CDE#TRPBF is most suitable for applications where the programmable output voltage, non-isolated point of load (POL) regulation, and high efficiency are required.

Examples of such applications include: external computer boards such as a graphics cards, notebook adapters, AC/DC adapters, automotive applications, DC/DC converters, server and telecom systems, and much more.

Working Principle

The LTC4355CDE#TRPBF operates by allowing the user to program the output voltage via an external voltage regulator to the activity desired. The controller then uses an internal regulator to control the terms of the output current by adjusting the output voltage accordingly. This ensures the output voltage is kept within the precise desired range regardless of load changes. The output current is further limited by the current sense resistor connected between the controller and the load, which also helps to prevent output overloads.

The LTC4355CDE#TRPBF also contains an integrated ideal diode and driver, which helps to provide protection to the load. When the output voltage falls below a certain value (the drop-out voltage, which is adjustable and is usually 3V or below), the ideal diode short-circuits the output to the input, preventing damaging reverse currents and ensuring that the load remains protected.

Finally, the LTC4355CDE#TRPBF also includes a shutdown input and a reset output, giving thesystem designer more flexibility for configuration and control.

Conclusion

In conclusion, the LTC4355CDE#TRPBF is a high-performance PMIC, combining the essential functions of a controller, ideal diode, and driver. It is ideal for applications requiring a programmable output voltage, POL regulation and high efficiency. With integrated protection features, the LTC4355CDE#TRPBF is an ideal choice when choosing a PMIC solution.
