The TPS61282EVM-586 is a Texas Instruments (TI) voltage boosting controller evaluation module designed to provide a stable voltage output for low-power applications. It is part of TI\'s evaluation module portfolio and is ideal for use in portable consumer and computing applications.

The TPS61282EVM-586 allows the user to select one of five selectable voltage outputs, including 3.3V, 3.3V with reset, 4V, 4.5V, and 5V. It also supports up to 1.8A of continuous current output. It utilizes a hydrid architecture and a synchronous buck-boost dc-dc converter topology. This topology allows it to boost voltage at light loads, reducing power consumption and optimizing efficiency.

The TPS61282EVM-586, like all TI evaluation modules, is designed with a focus on safety and reliability. It comes with built-in protection features such as over-voltage, short-circuit, over-temperature, and over-current protections. Additionally, the module comes pre-assembled, populated, and tested with the components necessary to evaluate the converting performance.

The TPS61282EVM-586 is a controller IC used as an off-line DC/DC & AC/DC (off-line) SMPS. The device is designed to allow users to start an "intelligent" design process by providing them with a complete application-specific evaluation platform.

The device has a single-stage synchronous buck-boost controller topology, which makes it suitable for applications that operate from an input voltage source between 1.8V and 5.5V. A current-mode architecture is used in the device to achieve fast transient response and improved transient response. The device also includes two enable pins, which allow for load shedding and fast-start control.

The device utilises a two stage architecture in which the first step is a buck-boost switching circuit which is used to boost the input voltage to generate the desired output voltage. The second stage is an internal voltage regulator to allow for stable output voltage. The internal voltage regulator is enabled when the load demand is higher than the available power from the first stage.

The device also consists of a switch-mode power supply control section, which is used to regulate and control the switch-mode power supply (SMPS) system. The SMPS system consists of a feed-forward and dynamic boost control technique, a pulse-width modulated (PWM) converter with seven voltage ratings, and a voltage-mode controller.

The TPS61282EVM-586 can be used for variety of applications, including automotive systems, medical equipment, entertainment systems, industrial control systems and communication systems. It is also suitable for use in battery-powered applications such as consumer electronics and portable devices. The device also comes with documentation and evaluation software to help the user in their design process.
