The LT3973EMSE-3.3#TRPBF is a fully integrated high voltage synchronous buck switching regulator from Linear Technology. It is part of the DC-DC switching regulators by Linear Technology in its line of power management integrated circuits (PMICs). The LT3973EMSE-3.3 is designed to provide efficient, step-down, low ripple DC power supplies from 3.3 V input and is capable of delivering up to 3.3 A of current. It features over-voltage protection, over-current protection and output voltage monitoring, all of which make it an ideal solution for many power conversion applications.

The LT3973EMSE-3.3#TRPBF is ideal for powering extremely low-noise, high-efficiency DC/DC converter applications in a variety of end markets, including automotive, industrial, medical and consumer electronics. It is also an excellent choice for powering FPGAs, PLLs and other integrated circuits that require tightly regulated supply voltages with very low ripple and noise. Due to its low RDS(ON) of 0.2mΩ and high switching frequency, it is an attractive solution for power cyclers and power over Ethernet (PoE) applications requiring high efficiency and low power dissipation.

The LT3973EMSE-3.3#TRPBF is a monolithic synchronous buck switching regulator with integrated power MOSFETs that offer extremely low RDS(ON) for maximum energy efficiency. The buck switching regulator accepts an input voltage of up to 33-volt and can deliver an output voltage of up to 3.3-volt with currents up to 3.3A. Its extremely high switching frequency, 1.2MHz allows for fast transient response, making it an ideal choice for noise-sensitive applications.

The LT3973EMSE-3.3#TRPBF provide several advanced features, including Over Voltage Protection (OVP), Over Current Protection (OCP) and Output Voltage Monitoring (OVM). The OVP and OCP circuits protect the device by limiting the output voltage and current, when necessary. The OVM monitors the output voltage and reports any fault conditions to the external host controller or microprocessor.

In addition, the LT3973EMSE-3.3#TRPBF offers a soft-start feature which allow for a smooth start-up and eliminates inrush current, and a selectable frequency synchronization feature that allows for the switching frequency to be synchronized with an external clock for easy EMI filtering. It also provides a power-good signal to report operational status and external circuitry for a track-and-hold feature which provides clean output waveforms.

The LT3973EMSE-3.3#TRPBF has a wide application field, including automotive, industrial, medical and consumer electronics, FPGAs, PLLs and other integrated circuits, power cyclers and Power-over- Ethernet (PoE) applications. Its integrated MOSFETs, OVP, OCP, OVM and other features makes it an ideal device for high-efficiency, low-noise power supplies. The LT3973EMSE-3.3#TRPBF is the the ideal solution for these applications providing a cost-effective, high-performance high-voltage switching regulator solution.
