LTC3536IM

series introduction

# Introduction to the LTC3536IM Product Series

## 1. Overview
The LTC3536IM is a highly versatile and efficient product series within the realm of power management integrated circuits (PMICs). Designed by Linear Technology (now part of Analog Devices), these devices are engineered to meet the demanding power requirements of a wide range of applications, from portable consumer electronics to industrial and automotive systems.

## 2. Key Features

### 2.1 High - Efficiency Power Conversion
- The LTC3536IM series utilizes advanced switching regulator technology to achieve high efficiency in power conversion. This is crucial for applications where power consumption needs to be minimized, such as in battery - powered devices. By reducing power losses during the conversion process, the device helps to extend the battery life of portable electronics, making it an ideal choice for smartphones, tablets, and wearables.
- It can operate with high efficiency over a wide input voltage range, typically from 2.7V to 5.5V. This allows it to be powered by various sources, including single - cell lithium - ion batteries, USB ports, or other low - voltage power supplies.

### 2.2 Multiple Outputs
- One of the standout features of the LTC3536IM is its ability to provide multiple regulated outputs. It can generate up to three independent output voltages, which can be configured to meet the specific power requirements of different components within a system. For example, in a mobile device, one output can be used to power the processor core, another for the memory, and a third for the display.
- The output voltages are adjustable, giving designers the flexibility to fine - tune the power supply for optimal performance. The output voltage ranges can be set within a wide spectrum, enabling compatibility with a variety of integrated circuits and other electronic components.

### 2.3 Low Quiescent Current
- The series has a very low quiescent current, which is the current consumed by the device when it is in standby or idle mode. This is an important feature for battery - powered applications, as it helps to conserve battery energy during periods of inactivity. The low quiescent current ensures that the device does not draw excessive power when the system is not fully operational, further enhancing the overall power efficiency of the system.

### 2.4 Integrated Protection Features
- To safeguard the connected components and the device itself, the LTC3536IM is equipped with a comprehensive set of protection features. These include over - current protection (OCP), over - voltage protection (OVP), and thermal shutdown.
- Over - current protection prevents the device from supplying excessive current to the load, which could damage the load or the power supply itself. Over - voltage protection ensures that the output voltage does not exceed a safe level, protecting sensitive components from voltage spikes. Thermal shutdown activates when the device temperature exceeds a certain threshold, preventing overheating and potential damage to the device.

## 3. Applications

### 3.1 Portable Consumer Electronics
- In smartphones and tablets, the LTC3536IM can be used to power the various subsystems, such as the CPU, GPU, memory, and display. Its high efficiency and multiple output capabilities make it well - suited for these power - hungry devices, helping to optimize battery life and improve overall performance.
- Wearable devices, such as smartwatches and fitness trackers, also benefit from the LTC3536IM's low quiescent current and small form factor. These devices require a compact and efficient power management solution to fit within their limited space and to operate for extended periods on a single battery charge.

### 3.2 Industrial Applications
- In industrial control systems, the LTC3536IM can be used to power sensors, microcontrollers, and other electronic components
