The TPS65580PWPR is a monolithic integrated DC to DC converter and Power Management IC (PMIC). It is part of the TPS65580 family of DC to DC converters with integrated power management and is designed for SoC applications powered from lithium ion batteries or a wide range of input supplies.

The TPS65580PWPR offers the smallest footprint for its class for a full featured PMIC without compromised performance. It provides low EMI, high efficiency and low quiescent power for portable applications. With its integrated power train, the TPS65580PWPR eliminates the need for board routing to manage multiple power rails.

The TPS65580PWPR is designed to manage multiple DC/DC converters, linear or buck type, simultaneously. The DC/DC converters can operate in forced PWM mode, burst mode operation and described by an arbitrary I2C configuration.

The TPS65580PWPR application field includes low power, battery powered embedded systems, cell phones and portable electronic products, such as PDAs, digital cameras and MP3 players. It can also be used in non-portable applications, such as CCTV and set-top boxes, where high efficiency is required.

The TPS65580PWPR integrates three buck regulators and four linear regulators, which are configurable in multiple combinations to generate the different power domains on modern electronic systems. Each buck regulator is capable of delivering up to 3A of current and the linear regulators up to 500mA, also each DC/DC converter and linear regulator is protected with built-in short circuit and over-temperature monitors.

The TPS65580PWPR also integrates a power supply sequencer, which controls the power up/down sequence of the different power supplies, thus ensuring a reliable power-on/off operation of the system. The power supply sequencer also provides protection against inrush current.

The TPS65580PWPR also integrates a programmable charger for single cell lithium-ion batteries and a clock generation module for clocking the DC/DC converters and the other system peripherals.

The TPS65580PWPR also integrates a very low power high accuracy RTC, and clocks for the system peripherals, programmable charger for single cell lithium-ion batteries, a compatibility interface for interfacing with and powering peripherals, and a programmable button controller for controlling the system\'s power-on and power-off functions.

The main advantage of the TPS65580PWPR is its working as a DC/DC switch mode controller. It performs DC/DC switching when it converts between the two DC voltages, thus providing high efficiency and very low power consumption. The high conversion efficiency of the TPS65580PWPR allows it to operate the system with lower losses, thus enabling a longer operation time with the same amount of energy input.

The TPS65580PWPR integrates a number of features that increase its robustness and makes it suitable for use in mission-critical applications. These features include over-voltage protection, over-current protection, under-voltage protection and thermal protection.

The TPS65580PWPR is a programmable regulator and its core circuitry, including voltage and current control, can be programmed through an I2C interface. This allows for flexible implementation of the DC/DC converter and linear regulator capabilities.

The TPS65580PWPR features a programmable charge pump regulator, an active clamping circuit and an internal bi-directional current limiter. The programmable charge-pump regulator enables the system to operate from low voltage power supplies of up to 4.0V. The active clamping circuit limits the output current of the DC/DC converters, thereby preventing overcurrent conditions in the system.

In conclusion, the TPS65580PWPR is a robust, high performance DC to DC converter and power management IC that provides low EMI, high efficiency and low quiescent power for portable applications. It integrates a range of features that are designed to improve the performance, safety, and efficiency of the system. This makes the TPS65580PWPR an ideal choice for a variety of applications.
