Introduction

LT3579EUFD#TRPBF is a switching regulator that belongs to the category of Power management integrated circuit (PMIC) - Voltage regulators - DC/DC switching regulators. It provides a minimum of 1.235V/1mA, a maximum of 5.5 V/1mA, and can output power up to 40W. It has a fixed-frequency PWM control, current-mode control scheme, and voltage feedback options. It is a high-efficiency, high-temperature, and low-noise solution for a wide range of applications such as portable electronics, mobile phones, and battery-powered products.

Function and Working Principle

The LT3579EUF#TRPBF is a buck DC/DC converter. It is designed to deliver a regulated voltage from an input source by stepping down the input voltage. In the buck DC/DC converter, a high-side MOSFET (metal-oxide-semiconductor field-effect transistor) and a low-side MOSFET are configured as a pair. The upper MOSFET is used as an input switch, while the lower MOSFET is used as the output switch. The power is transferred from the input to the output by turning these MOSFETs on and off.The LT3579EUF#TRPBF switching regulator also features a current-mode control scheme. In this scheme, the error amplifier compares the feedback voltage and the reference voltage to generate a current that is proportional to the difference between the two. This current is then used to control the operation of the buck converter, by controlling the on and off times of the MOSFET switches.The LT3579EUF#TRPBF also features a fixed frequency PWM control. This feature allows the regulator to accurately control the output voltage with minimal ripple and noise.
