The LTC3374AIUHF#TRPBF is an integrated switching regulator for motor control, high-performance power conversion, and LED driving solutions with simple circuit solutions. It belongs to the DC DC switching regulator family of PMIC (Power Management IC) voltage regulator products and is designed to operate with a PWM (Pulse Width Modulation) switching frequency of up to 1MHz. It operates over a wide input voltage range of 4.5V to 75V, offering a high-performance solution for a variety of applications such as server and communications systems, robotics, automotive, industrial, and many other applications.

The built-in control unit embeds pre-defined motor profiles for the purpose of motor control. The motor control profile setting can be internally set up, or set up remotely via external programming logic. The internal regulator can also provide adjustable speed control, providing a wide range of operation, from low to high speeds.

The integrated current sense with overcurrent fault detection significantly improves the robustness of the system by providing a wide range current range, along with the protection against short circuits or overloading of motor, making the system more secure for a broad range of motor control applications such as medical, industrial, and robotic applications.

The LTC3374AIUHF#TRPBF DC DC switching regulator supports a wide input voltage range of 3.3V to 75V, along with output voltage range of 0.5V to 6V, providing an efficient and reliable method of supplying power to a variety of end applications, such as industrial equipment, communication systems, and robotic applications. In addition, it supports adjustable output current mode and voltage mode control, enabling precise and smooth regulation.

It supports current mode control (CMC) and voltage mode control (VMC) with a peak current control (IPC) option for improved current ripple control. The programmable standby and output regulation currents eliminate potential problems such as load fluctuations and vibrations.

The LTC3374AIUHF#TRPBF DC DC switching regulator also supports a wide range of adjustable switching frequency range from 200kHz to 1MHz, enabling the application to be used for higher power and performance requirements. The adjustable compensation ensures precise regulation of output voltage and helps in maintaining the stability of the entire system.

The power supply rejection ratio (PSRR) on this device is typically high, therefore minimizing the susceptibility of the system to the noise in the input signal. The adaptive on-time (AOT) control feature provides improved light load efficiency, enabling it to maximize conversion efficiency at all output conditions. The IC also offers protection against overvoltage, undervoltage and short circuits.

In addition, the LTC3374AIUHF#TRPBF DC DC switching regulator also supports a wide temperature range of -40°C to 85°C and is available in an automated board placement ready low-profile, RoHS-compliant, QFN package. This combination of features makes the LTC3374AIUHF#TRPBF ideal for a broad range of motor control, high-performance power conversion and LED driving solutions.
