The LTC3864HDE#TRPBF provides a voltage-mode control to regulate the output voltage by sensing the output voltage with the Error Amplifier. The Error Amplifier compares the output voltage with the reference voltage and adjusts the on-time of the two MOSFETs accordingly. This on-time is set by an internal clock that can be scaled or wired externally synchronizing with multiple converters. As the load is changed, the output voltage is changed accordingly and the Error Amplifier adjusts the on-time to maintain the output voltage constant. With this control method, the LTC3864HDE#TRPBF achieves high efficiency with excellent accuracy and quick response.

In conclusion, the LTC3864HDE#TRPBF is a high-performance, two-phase, synchronous buck regulator controller. It is designed to drive the two N-channel MOSFETs in a fixed-frequency, voltage-mode step-down regulator circuit. It has a wide range of features and offers excellent accuracy, excellent transient response, and high efficiency over a wide range of input and load conditions. It is ideal for use in applications such as high-current computing and telecom power supplies, thanks to its advanced control features and wide adjustment range.
