The TLC59208FIRGYR is a multi-channel power management integrated circuit (PMIC) developed by Texas Instruments. It is part of the LED Drivers family, which are specifically designed to drive LED’s with elevated accuracy and efficiency. The TLC59208F is a highly efficient LED driver designed to reduce system power consumption when driving several LED channels.

The TLC59208F is equipped with 8 high-efficient low-side channels and each individual channel is configurable to drive up to 2 LEDs in bipolar connection. Moreover, the TLC59208F has an integrated PFC (Power Factor Correction) circuit and an optimized architecture design which make it one of the most efficient LED driver ICs in the market.

The TLC59208F is designed to be used in applications such as LED displays, LED lighting, LED backlighting, LED TV, LED signs, LED scanners and LED printers. It can also be used in automotive systems including side lighting and dashboard lighting. It delivers a maximum output voltage of 16V, a maximum output current of 200mA and a minimum operating temperature of -40C.

When it comes to the working principle of the TLC59208F, its main function is to reduce the size of the system and minimize power consumption while driving multiple LED channels. Its PFC circuit was designed to help the power supply achieve a power factor greater than 0.98, resulting in improved system efficiency. Additionally, its architecture design enables the TLC59208F to shift the power supply ‘duty cycle’ so that peak current is reduced. Moreover, its high efficiency enables the TLC59208F to remain cooler, resulting in better thermal management and improved reliability.

The TLC59208F is capable of driving both constant current and constant voltage. When used for constant current mode, the TLC59208F uses two sets of control pins to set the current level of each individual channel. In constant voltage mode, the TLC59208F uses an external reference voltage which is then converted by the on board regulators. Additionally, the chip provides an open LED protection to ensure that LEDs are not damaged due to accidental open circuits.

The TLC59208F comes with integrated Power-On-Reset (POR) function, a configurable auto-PWM dimming mode, an integrated thermal protection and an over-temperature protection. The POR circuit will reset the power supply when the voltage level drops below a certain standard. The auto-PWM dimming mode uses a PWM signal as an input which allows users to adjust the brightness of their LEDs for improved efficiency. The thermal and over-temperature protection ensure that the chip remains with a safe power level.

In conclusion, the TLC59208F is an efficient and reliable 8-channel LED driver IC which can be used for driving multiple LED channels. Its PFC circuit and optimized architecture design allow the TLC59208F to reduce system power consumption while maintaining high efficiency. Additionally, its thermal and over-temperature protections and integrated POR circuit ensure that the chip and the LEDs are protected against any accidental damage.
