Application field of the TPS61177AEVM

The TPS61177AEVM evaluation module is specifically designed for LED driver applications. It provides a complete design platform for evaluating the performance of the TPS61177 boost converter IC. This board is suitable for driving LEDs from an input voltage of between 5.5 V and 45 V. It can deliver a regulated output voltage from 5 V to 24 V. This board also includes a dimming control input, allowing the output current to be adjusted.

The output of this board can drive up to 350 mA of current, making it suitable for applications such as LED displays, streetlights, automotive lighting, and CCTV camera lighting. Additionally, this board can be used in applications such as LCD backlight dimming and daylight harvesting, which require the power supply to adjust the output current based on the ambient light level.

This board is also suitable for use in industrial and medical lighting applications. It can be used to drive a constant current LED load, providing a high-efficiency solution while still maintaining a low operating temperature. It also offers protection against short circuits, over-temperature, and over-voltage conditions.

Working principle of the TPS61177AEVM

The TPS61177AEVM evaluation module works by using the TPS61177 boost converter IC to increase the input voltage to the desired output voltage. The boost converter uses a switched capacitor to step up the voltage. When it is off, the capacitor is charged to the input voltage. When it is switched on, the capacitor discharges through an inductor, boosting the voltage. The switching frequency of the boost converter is controlled by an external clock signal.

The adjustable output voltage of this board is set using a potentiometer. The output current is adjusted using a dimming control input, allowing the current to be adjusted from 50 mA to 350 mA. The board also includes a power-on reset function, which turns off the board when the input voltage drops below a certain threshold.

The TPS61177AEVM EVM has a number of safety features to protect users. It includes an over-temperature protection feature that shuts down the power supply if the temperature rises above a certain threshold. It also includes an over-voltage protection feature that turns off the power supply if the output voltage is too high. Finally, the board also has an under-voltage lockout feature, which prevents the board from trying to boost the input voltage if it is too low.

The TPS61177AEVM EVM is suitable for a variety of LED driver applications. It provides a complete design platform for evaluating the performance of the TPS61177 boost converter IC. It is capable of delivering a regulated output voltage from 5 V to 24 V, with a current up to 350 mA. It also includes a dimming control input, allowing the output current to be adjusted. Additionally, it includes a number of safety measures to protect users from a variety of conditions. Overall, the TPS61177AEVM EVM is an excellent choice for LED driver applications.
