The LT1764AEQ-3.3#TRPBF is a family of high-performance, high-frequency DC/DC step-down switching regulators, which have been designed for use in a variety of low-power systems. As a member of the Linear Voltage Regulators family of products, the LT1764AEQ-3.3#TRPBF is a direct-driven or synchronous buck-converter which allows for dynamic adjustment of output voltage to a wide range of supply voltages. The LT1764AEQ-3.3#TRPBF is capable of operating at a frequency up to 2MHz and delivering up to 3.2W of power efficiency. It also features low-noise operation, fast transient response and a high set-point accuracy.

The LT1764AEQ-3.3#TRPBF is designed primarily as a voltage regulator and as such, it can be applied in a variety of applications such as distributed power systems and SEPIC converters. As a voltage regulator, the LT1764AEQ-3.3#TRPBF can be used to regulate the output voltage of a power supply, to provide a consistent voltage source to a load, regardless of the input voltage. The LT1764AEQ-3.3#TRPBF can also be employed as a switch-mode power supply (SMPS) to convert a higher input voltage to a lower output voltage, as required for many electronic applications. As a DC/DC switching regulator, the LT1764AEQ-3.3#TRPBF is capable of providing output power conversion efficiency up to 97%.

The LT1764AEQ-3.3#TRPBF operates in a buck topology; a switching converter that regulates the output voltage by controlling the duty cycle of a switch. The output voltage is regulated by a voltage-mode control. This type of control uses an internal error amplifier to sense the output voltage, adjusts the duty cycle of the switch according to the feedback voltage, and ensures that the output voltage is regulated within a specific range. In addition, the maximum duty cycle of the LT1764AEQ-3.3#TRPBF can be limited using an external resistor. This helps prevent the output voltage from exceeding its desired level even if the input voltage is higher than expected.

The LT1764AEQ-3.3#TRPBF also utilizes current-mode control, which senses the output current and regulates the current so that the output voltage remains within a specific range. This feature helps to increase the efficiency of the converter and reduces output ripple, resulting in better overall performance. Furthermore, the LT1764AEQ-3.3#TRPBF features a current-limiting system, which helps to reduce short-circuit currents and provide protection for the load.

The LT1764AEQ-3.3#TRPBF also provides protection against overcurrent and overvoltage conditions. In the event of an overvoltage or overcurrent, the LT1764AEQ-3.3#TRPBF will shut down the output to protect the system. Additionally, the LT1764AEQ-3.3#TRPBF features high-side and low-side MOSFETs with integral diodes, which helps to reduce component count, reduce cost and help increase system reliability by eliminating the need for additional external components.

The LT1764AEQ-3.3#TRPBF is ideally suited for a variety of space-constrained, high frequency power conversion applications. Its high efficiency, fast transient response, wide input voltage range, and high output current make it an ideal solution for distributed power systems, as well as converters for computing, consumer electronics, and industrial applications.
