The LT3048IDC-3.3#TRPBF is a step-down DC/DC power module from Linear Technology’s low-noise, high voltage Power Path product portfolio. The LT3048IDC-3.3 voltage regulator provides high efficiency and low ripple for optimal power management and sequencing capabilities. It is designed for use with off-the-shelf controllers, or custom power management solutions from Linear Technology.

Application Field of LT3048IDC-3.3#TRPBF

The LT3048IDC-3.3 voltage regulator is designed to provide high-performance, high-efficiency power solutions for applications requiring 3.3V, 4.2V, or 5V output voltage and up to 15A output current. It is suitable for a wide range of applications such as computing, networking, industrial, communication, commercial, automotive and motor control.

The LT3048IDC-3.3 can be used in applications requiring an adjustable output voltage and features on-board voltage loop compensation and current limit control, as well as remote sensing of both voltage and current. This makes it an excellent choice for battery-powered and system-powered applications requiring a wide input voltage range, low noise, and maximum efficiency.

Working Principle of LT3048IDC-3.3#TRPBF

The LT3048IDC-3.3 voltage regulator utilizes a linear regulator and a buck converter in parallel to regulate the output voltage. The linear regulator provides the higher voltage and current capability, while the buck converter provides the higher efficiency and low ripple. The output voltage is controlled by the linear regulator and can be adjusted over a wide range. A low-noise, adjustable current limit control is also included for applications requiring current limit protection.

The LT3048IDC-3.3 also features a wide input voltage range of up to 24V, which reduces the number of components required and ensures that the regulator can be used in applications with wide input voltage range. Its current limit, remote sensing and adjustable output features make it an ideal choice for power and sequencing applications.

The LT3048IDC-3.3 features high efficiency (up to 92% at 5V/15A), low output ripple (0.03% peak-to-peak), dynamic response (500kHz), low quiescent current (less than 1mA), and adjustable current limit. These features make it suitable for a wide range of applications, including computing, networking, industrial, communication, commercial, automotive and motor control applications.
