series introduction

# TPS61160 Product Series Introduction

## 1. Overview
The TPS61160 product series is a remarkable collection of integrated circuits (ICs) developed by Texas Instruments, designed to address the critical need for efficient power management in a wide range of electronic devices. These devices are specifically engineered as high - efficiency boost converters, capable of taking a low - voltage input and converting it into a higher, regulated output voltage. This makes them an ideal choice for applications where power sources may have limited voltage levels, but higher voltages are required to drive various components.

## 2. Key Features

### High Efficiency
One of the most prominent features of the TPS61160 series is its high efficiency. These boost converters can achieve efficiency levels of up to 96%. This high efficiency is crucial as it minimizes power losses during the voltage conversion process. In battery - powered devices, for example, high efficiency translates into longer battery life, as less energy is wasted as heat. This not only improves the overall performance of the device but also reduces the need for complex and bulky heat - dissipation mechanisms.

### Wide Input and Output Voltage Range
The TPS61160 series offers a wide input voltage range, typically from 0.9 V to 5.5 V. This flexibility allows it to be used with a variety of power sources, such as single - cell lithium - ion batteries (which typically have an output voltage in the range of 3.0 - 4.2 V), multiple alkaline batteries, or other low - voltage power supplies. On the output side, it can provide regulated voltages up to 18 V, making it suitable for driving a wide range of loads, including LEDs, small motors, and other high - voltage components.

### Adjustable Output Voltage
The output voltage of the TPS61160 can be easily adjusted using external resistors. This feature provides designers with the flexibility to tailor the output voltage to the specific requirements of their application. Whether it's a 5 V supply for a microcontroller or a higher voltage for driving a string of LEDs, the adjustable output voltage allows for a customized power solution.

### Low Quiescent Current
The TPS61160 series has a very low quiescent current, typically in the range of a few microamps. This is especially important in battery - powered applications where the device may spend a significant amount of time in a standby or low - power mode. The low quiescent current ensures that the battery drain is minimized during these periods, further extending the battery life.

### Integrated Protection Features
These devices come with a comprehensive set of integrated protection features. Over - current protection (OCP) prevents the device from drawing excessive current, which could damage the components or cause a safety hazard. Over - voltage protection (OVP) ensures that the output voltage does not exceed a safe level, protecting the connected load from voltage spikes. Thermal shutdown protection automatically shuts down the device if the temperature exceeds a certain threshold, preventing overheating and potential damage to the IC.

## 3. Applications

### Portable Electronic Devices
In portable devices such as smartphones, tablets, and wearable devices, the TPS61160 series plays a vital role in power management. These devices often rely on small, low - voltage batteries, but require higher voltages to drive components such as the display backlight, audio amplifiers, or wireless communication modules. The high - efficiency and low - quiescent current of the TPS61160 make it an ideal choice for extending the battery life of these portable devices.

### LED Lighting Systems
LED lighting is becoming increasingly popular due to its energy - efficiency and long lifespan. However, LEDs typically require a specific forward voltage to operate properly. The TPS61160 can be used to boost the
