TPS61080EVM-147 is an evaluation board used in LED Drivers, specially designed to evaluate the operation of the TPS61080 synchronous buck converter. This device incorporates a wide input voltage range of up to 6V, exerting a maximum output power of up to 4.5W. Additionally, it is an efficient solution for space-constrained systems.

The board features an adjustable output voltage of 5.5V through a voltage sense resistor as well as an adjustable output current of up to 1A. It also has an integrated power switch and a wide range of features such as input or output overvoltage protection, automatic soft-start ramps, an undervoltage protection, an over-temperature protection feature, and a fault flag.

The TPS61080EVM-147 is a great option for being used on systems that require precision, reliability and efficiency. Its small size makes it perfect for being used in applications with limited space constraints, such as mobile phones and tablets. Additionally, its low ripple, its low input/output cross regulation, and its wide operating temperature range of -40°C to +85°C make it an ideal choice for regulating power supplies.

When it comes to working principles, the TPS61080EVM-147 starts when the load enables the output voltage. The device steps down the input voltage to an adjustable output voltage as determined by the external voltage sense resistor divider. This synchronous buck/boost converter features a peak current-mode control, allowing proper control of the current delivered to the load. The power switch is enabled for very short turn-on/turn-off transitions, which makes the device maintain its high efficiency at low output power.

Aside from the already mentioned features, TPS61080EVM-147 has a handful of additional features that make it a better option for regulating step-down power supplies. With its wide input range, the device allows for very high input voltages to be regulated, while its wide operating temperature range makes it suitable for harsh environments. Additionally, its adjustable output current is great for systems that require up to 1A of output current, while its low quiescent current reduces the power loss and improves the efficiency.

Overall, the TPS61080EVM-147 is a great device for applications that require a reliable, efficient and high power converter. Its unique features, small size and wide operating temperature range make it the perfect choice for LED drivers, mobile phones, tablets and any other space-constrained systems.
