The LT3782AEFE¹ is a high efficiency DC-to-DC buck switching regulator controller with an integrated power MOSFET, designed to meet the demanding needs of applications such as embedded computers, networking equipment and server platforms. The LT3782AEFE is a fully integrated, low component count solution that offers high efficiency and simplicity of installation, while supporting flexible configuration options with a single instruction register and the ability to synchronize to an external clock. It offers superior load regulation, line regulation, current limit, output control and protection features. This makes it the ideal solution for many DC-to-DC switching regulator applications.

The LT3782AEFE is powered by a regulated, synchronous, buck-mode voltage regulator switch controller with a low-side floating synchronous rectifier. The regulator chip is equipped with a programmable, 200 kHz or undivided-by-four frequency, integrated switching power MOSFET and a thermal protection option. The LT3782AEFE can operate as a stand-alone controller, as well as a regulator-on-a-chip solution by adding a few discrete components. The LT3782AEFE’s power MOSFET allows it to support output currents up to 10 A, making it ideal for high power applications.

The LT3782AEFE has a wide operating input voltage range, from 7 V to 28 V and an adjustable output voltage range from 0.8 V to the input voltage and it allows for both a high and a low-side current sense resistor to achieve accurate current measurements and monitoring, or a single current sense resistor for an average current mode of operation. The device also supports a wide range of output power levels making it suitable for a variety of different applications.

The LT3782AEFE is a highly flexible DC-to-DC buck regulator, offering adjustable operating frequency and output voltage, power tracking, PFM/PWM flexibility, programmable soft-start and programmable fault protection. It is designed to operate in environments with large temperature variations and high EMI levels, supporting up to 29V operating voltage, and has several fault protection features. This makes it an ideal regulator for applications such as HDD/SDD power supplies, set-top boxes and other embedded systems.

The LT3782AEFE switching regulator also offers several new switching mode control architectures that greatly improve efficiency and transient response compared to existing controllers. The architecture includes a variable frequency buck regulator, programmable pulse width modulation (PWM) operation, a variable-frequency, variable-duty cycle control mode that improves dynamic response and a unique low-side pre-charge control to reduce output glitches. The device also offers a power-down control that slows down the switching frequency when the output is less than one quarter of its maximum value, reducing noise in the system.

In Summary, the LT3782AEFE is an ideal IC for DC/DC voltage regulation and provides a highly-integrated and cost-effective solution for a wide variety of applications. With its advanced control architecture, wide operating voltage range, and easy-to-use configuration options, the LT3782AEFE is an excellent choice for applications such as embedded computers, networking equipment, server platforms, and HDD/SDD power supplies.
