TLC6C5712EVMs represent an interesting breed of power devices in the Evaluation Boards- LED Drivers domain. In this article we will discuss its application field as well as its working principle.

TLC6C5712EVMs is an evaluation board module (EVM) that uses Texas Instruments TLC6C5712 Constant-Current LED Driver. This device is used to control the current delivery to LEDs, providing regulation and potentially eliminating the need for further external components.

This device has the capability of handling up to 10 LEDs in parallel and has a 2.3V to 3.3V voltage range, thus avoiding the problem of too many convoluted circuit components. Its current range is from 0 to 150mA with 2mA steps, ensuring precise light intensity control. Moreover, the device can be turned on and off quickly, allowing for fast and efficient transitions.

Furthermore, the board also integrates many components like enable and latch pins, MOSFETs or resistors along with external inputs from a PC amplifiers or logic control boards. Temperature sensors and the possibility of using the board with different currents are only some of the possibilities this board has to offer.

The most important application field of the TLC6C5712EVM is in the area of LED light installations. With the push of a button you can control the current delivery to multiple LEDs, thus providing exact and consistent light intensity levels. It can be used in indoor and outdoor installations, with different types of bulbs and colors.

The working principle of the TLC6C5712EVM is based on the Texas Instruments TLC6C5712 Constant-Current LED Driver. This device is a constant current regulator that is used to deliver exact amounts of current to each LED or LED string. It integrates several features, like a Low Drop Out (LDO) voltage regulator, an I2C interface, and a wide range of operating voltages (2.3V to 3.3V).

The I2C interface is used to select the current of each LED string and for communication with other boards. The LDO voltage regulator is also used to provide precise voltage regulation and to ensure constant operation of LEDs even in case of large fluctuations in their operating voltage.

The internal circuitry of the TLC6C5712EVM is constructed using MOSFETs and resistors. The MOSFETs act as switches which can be controlled via digital signals to increase/decrease the current delivery of each LED string. The resistors are integrated to limit the current flowing through each string.

To sum up, the TLC6C5712EVM is a powerful and flexible device which enables precise control of LED power. It can operate from 2.3V to 3.3V, allowing for operation in different assembly environments. Moreover, the board is able to control up to 10 LEDs in parallel, making it suitable for a wide range of applications.
