The LM2574HVM-3.3/NOPB is a Voltage Regulator and is part of a wide range of DC- DC Switching Regulators offered by Texas Instruments. It is designed to operate from a wide input voltage range, making it perfect for low noise circuits and applications such as portable equipment or battery-powered systems.

This device features a maximum output current of 10A, with a 3.3V nominal output voltage. It features a synchronous buck architecture that offers optimal efficiency over a wide load range, and allows for fast transient response. It also includes two low-dropout voltage regulators that provide up to 150mA of total load current.

The LM2574HVM-3.3/NOPB employs a fixed-frequency peak current mode control, allowing for simple external components. It also features an automatic low-frequency pulse skipping during light load conditions which reduces the output ripple, and minimizes the impact of input glitches and disturbances.

The LM2574HVM-3.3/NOPB utilizes a single startup resistor to adjust the current limit and enable power good indication for pre-biased outputs. It also incorporates a low-voltage handling feature, which automatically reduces its output current limit during a lightly loaded start-up or during light load conditions, improving its output voltage accuracy.

The device also includes Hicrest™, which is a proprietary current-mode peak current-mode control with enhanced transient response. This control allows for faster loop compensation, reduced output ripple and superior line regulation. The LM2574HVM-3.3/NOPB also includes current-limit circuitry which enables protection against overcurrent conditions.

The LM2574HVM-3.3/NOPB incorporates advanced protection features such as overvoltage protection, overcurrent protection, and auto-recovery thermal shutdown. The built-in soft-start feature provides a controlled ramp-up of the output voltage, and the device is protected from output short-circuits and overcurrent faults.

The LM2574HVM-3.3/NOPB is designed to operate from a wide input voltage range, allowing it to be used in many different application fields. It is designed for use in wireless communication, industrial equipment, automotive, and audio systems. It is also suitable for portable equipment and battery-powered systems, making it a great choice for such applications.

In conclusion, the LM2574HVM-3.3/NOPB is a great choice for voltage regulation and power management applications. It provides a wide input voltage range, maximum output current of 10A, and low-dropout voltage regulators that offer up to 150 mA of total load current.
