# LTM4619IV Product Series Introduction

## 1. Overview
The LTM4619IV is a highly advanced and versatile product series within the realm of power management solutions. Designed by a leading semiconductor manufacturer, this series offers a comprehensive set of features and capabilities that make it an ideal choice for a wide range of applications, from industrial equipment to consumer electronics.

## 2. Key Features

### 2.1 High - Efficiency Power Conversion
The LTM4619IV series is engineered to provide high - efficiency power conversion. It utilizes state - of - the - art switching regulator technology, which minimizes power losses during the conversion process. This not only helps in reducing energy consumption but also results in less heat generation, enhancing the overall reliability and lifespan of the system. For example, in a typical application, it can achieve conversion efficiencies of up to 90% or more, depending on the input and output voltage conditions.

### 2.2 Wide Input and Output Voltage Ranges
One of the standout features of the LTM4619IV is its wide input and output voltage ranges. The input voltage can typically accept values from a relatively low level, say 4.5V, up to a high of 38V. This wide input range makes it suitable for use in various power supply environments, whether it's a battery - powered system or a regulated DC power source. On the output side, it can provide a precisely regulated output voltage that can be adjusted within a specified range, usually from 0.6V to 5V. This flexibility allows it to power different types of loads, such as microcontrollers, FPGAs, and other integrated circuits.

### 2.3 Integrated Design
The LTM4619IV comes in a compact and integrated package. It integrates all the necessary components for a complete power supply solution, including the switching regulator, inductors, and input/output capacitors. This integrated design significantly simplifies the power supply design process for engineers. Instead of having to source and assemble multiple discrete components, they can simply use the LTM4619IV module, saving both time and board space. This is especially beneficial in applications where space is at a premium, such as in portable devices or compact industrial control systems.

### 2.4 Current Sharing and Parallel Operation
In applications that require higher output currents, the LTM4619IV series supports current sharing and parallel operation. Multiple LTM4619IV modules can be connected in parallel to increase the total output current capacity. The built - in current - sharing mechanism ensures that each module shares the load evenly, preventing overloading of individual modules. This feature makes it possible to scale the power supply according to the specific requirements of the application, whether it's a small - scale project or a large - scale industrial installation.

### 2.5 Excellent Transient Response
The LTM4619IV exhibits excellent transient response characteristics. When there is a sudden change in the load current, it can quickly adjust the output voltage to maintain a stable level. This is crucial in applications where the load can vary rapidly, such as in digital circuits where the power consumption can change significantly during different operating modes. The fast transient response helps to ensure that the connected devices receive a stable power supply, preventing malfunctions and data errors.

## 3. Applications

### 3.1 Industrial Automation
In industrial automation systems, the LTM4619IV can be used to power various control modules, sensors, and actuators. Its wide input voltage range allows it to be compatible with different industrial power sources, and its high - efficiency operation helps in reducing energy costs. The integrated design simplifies the installation and maintenance of the power supply in industrial environments, where reliability and space - saving are important considerations.
