series introduction

# LT3463EDD Product Series Introduction

## 1. Overview
The LT3463EDD is a highly versatile and efficient integrated circuit product series designed by Linear Technology (now part of Analog Devices). This series is specifically engineered to address a wide range of power management requirements in various electronic applications. With its advanced features and robust performance, the LT3463EDD offers a reliable solution for designers seeking to optimize power consumption and enhance system functionality.

## 2. Key Features

### 2.1 High - Efficiency Operation
The LT3463EDD series is built with a high - efficiency switching regulator topology. It can achieve high conversion efficiencies, typically up to 90% or more, depending on the input and output voltage conditions. This high efficiency helps to minimize power losses, reduce heat dissipation, and extend the battery life in portable applications. For example, in a battery - powered device, the reduced power consumption means longer usage time between charges, which is a crucial factor for user satisfaction.

### 2.2 Wide Input Voltage Range
It supports a wide input voltage range, which allows it to be used in diverse power supply scenarios. The input voltage can typically range from a few volts up to a relatively high value, such as 2.7V to 40V. This wide range makes it suitable for applications powered by different sources, including batteries, wall adapters, and automotive power systems. For instance, in automotive electronics, where the battery voltage can vary significantly during startup and normal operation, the LT3463EDD can maintain stable performance.

### 2.3 Adjustable Output Voltage
The output voltage of the LT3463EDD can be easily adjusted to meet the specific requirements of different loads. Designers can use external resistors to set the output voltage within a specified range. This flexibility enables the device to power a variety of components, such as microcontrollers, sensors, and other integrated circuits that may require different supply voltages.

### 2.4 Low Quiescent Current
In standby or low - power modes, the LT3463EDD has a very low quiescent current. This feature is essential for applications that need to conserve power when not in active use. For example, in a wireless sensor node that spends most of its time in a sleep state, the low quiescent current helps to minimize the overall power consumption and extend the battery life.

### 2.5 Integrated Protection Features
The series is equipped with a comprehensive set of protection features to ensure the safety and reliability of the system. These include over - current protection (OCP), over - voltage protection (OVP), and thermal shutdown. Over - current protection prevents the device from being damaged due to excessive current flow, while over - voltage protection safeguards the load from high - voltage spikes. Thermal shutdown protects the IC from overheating, which can degrade its performance and potentially cause permanent damage.

## 3. Applications

### 3.1 Portable Electronics
In portable devices such as smartphones, tablets, and wearable devices, the LT3463EDD can be used to manage the power supply. Its high efficiency and low quiescent current are ideal for extending the battery life of these devices. It can also provide stable power to various components, such as the display, processor, and wireless modules.

### 3.2 Automotive Electronics
Automotive applications require components that can withstand harsh environments and wide voltage variations. The LT3463EDD's wide input voltage range and robust protection features make it suitable for use in automotive infotainment systems, lighting systems, and sensor modules. For example, it can be used to power the LED headlights, ensuring stable and efficient operation.
