It is an integrated power solution designed to supply multiple points of power to a modern, distributed computing system and powered devices. This chipset boasts impressive performance, flexibility, and integration with an eye towards cost-efficiency. The LT3579IUFD#TRPBF belongs to the category of PMIC (Power Management Integrated Circuit) voltage regulator and more specifically in the sub category of DC-DC switching regulators. In this article, we will discuss the application field and working principle of the LT3579IUFD#TRPBF.

Applications of the LT3579IUFD#TRPBF

The chip is targeted for use in modern distributed computing systems where complex power distribution requirements and stringent point-of-power requirements are the norm. The device is specifically designed for power sequencing and sequencing shutdowns, buck-boost regulators, low battery detectors and high isolation Buck regulators. It has applications in Computer Gaming, Servers, Smartphones, Tablets, Automotive, Industrial Automation, Medical Devices and Embedded Applications.

In particular, in gaming, servers and military settings, extreme power performance and excellent power factor control capabilities are needed. This IC is ideal for such applications as it enables complex power system designs with stringent power requirements. In battery operated gadgets such as tablets, phones and other handhelds, the LT3579IUFD#TRPBF is perfect for the power delivery, due to its small size, high efficiency, fast response times and low quiescent current.

Working Principle of the LT3579IUFD#TRPBF

The basic working principle of the LT3579IUFD#TRPBF is synchronous buck converter with PFC (power factor correction). It contains a high-side driver, load switch, two independent low-side switches, voltage regulator, and power MOSFET (metal-oxide-semiconductor field-effect transistor) for controlling the drain current and regulating the output voltage. The PFC ensures efficient power distribution by optimizing the electrical characteristics of the source and load. The LT3579IUFD#TRPBF regulator provides controlled on-time operation of the PFC inductor and low output voltage ripple.

The LT3579IUFD#TRPBF also features a wide input voltage range from 9 V to 50 V and a wide output voltage range from 0.6 V to 40 V. It offers high efficiency and fast transient recovery with an adjustable current limit, soft start and on-demand reset with manual reset. The low quiescent current of 700 µA at full load with no load current of 85 µA ensure low operating temperatures and longer life cycle.

The LT3579IUFD#TRPBF combined with external components such as discreet MOSFETs and capacitors can provide a wide range of power management solutions. The chip can be used as single-channel or dual-channel voltage regulators. The single channel can independently control two output voltages for powering the processor core, memory and IO. The dual channel can provide dual-rail outputs required for DDR memory regulators. The chipset features a sophisticated sequencing tool, Pulse-Skipping ModeTM to support low power budget, lowest standby power, and improved efficiency.

The LT3579IUFD#TRPBF device transmitter is able to provide an enable pin between 0.4 V and 5.5V for on/off control for dual outputs. It also offers an enable pin for on/off control for single channel. It is suitable for both static and dynamic applications. The device has a reversible fault protection mechanism which enables discovery of continuous over-current or thermal shutdown faults.
