# TPS61059 Product Series Introduction
## Overview
The TPS61059 product series is a remarkable set of integrated circuits (ICs) developed by Texas Instruments, designed to address a wide range of power management needs in various electronic applications. 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.
## Key Features
### High Efficiency
One of the most prominent features of the TPS61059 series is its high efficiency. With advanced circuit design and power management techniques, these converters can achieve efficiency levels of up to 96%. This high efficiency is crucial in battery - powered applications as it helps to extend the battery life. By minimizing power losses during the voltage conversion process, less energy is wasted as heat, allowing the device to operate more effectively and for a longer period on a single battery charge.
### Wide Input and Output Voltage Range
The TPS61059 series offers a wide input voltage range, typically from 0.9 V to 5.5 V. This flexibility enables it to be used with a variety of power sources, such as single - cell or multi - cell batteries, solar panels, and other low - voltage power supplies. On the output side, it can provide a regulated output voltage that can be adjusted up to 28 V. This wide output voltage range makes it suitable for powering different types of loads, including LEDs, sensors, and other integrated circuits that require a higher voltage supply.
### Adjustable Output Current
These converters also allow for adjustable output current. This feature is highly beneficial in applications where the load requirements may vary. For example, in LED lighting applications, the brightness of the LEDs can be controlled by adjusting the output current. The TPS61059 series provides a convenient way to set the output current according to the specific needs of the load, ensuring optimal performance and energy efficiency.
### Low Quiescent Current
The TPS61059 series has a very low quiescent current, typically in the range of a few microamperes. Quiescent current is the current consumed by the converter when there is no load or when the load is very small. A low quiescent current is essential in battery - powered applications, as it helps to conserve battery power during standby or idle modes. This makes the TPS61059 series an ideal choice for applications that require long - term battery operation, such as wearable devices and wireless sensors.
### Integrated Protection Features
To ensure the reliability and safety of the system, the TPS61059 series comes with a number of integrated protection features. These include over - current protection (OCP), over - voltage protection (OVP), and thermal shutdown. Over - current protection prevents the converter from delivering excessive current to the load, which could damage the load or the converter itself. Over - voltage protection ensures that the output voltage does not exceed a safe level, protecting the connected components from voltage spikes. Thermal shutdown is activated when the temperature of the converter exceeds a certain threshold, preventing the device from overheating and potentially failing.
## Applications
### LED Lighting
The TPS61059 series is widely used in LED lighting applications, including backlighting for LCD displays, automotive interior lighting, and general illumination. Its ability to provide a regulated output voltage and adjustable output current makes it an excellent choice for driving LEDs. The high efficiency of the converter also helps to reduce power consumption and heat generation, which is important for the long - term reliability of the LED lighting system.
### Portable Devices
In portable devices such as smartphones, tablets, and wearable devices, the TPS61059 series can be used to boost the battery voltage to a level suitable for powering the various components.
