The TLC5930PWP is a PMIC - LED Drivers. It is a Texas Instruments advanced light emitting diode (LED) driver with additional features such as thermal protection, dimming control, and power circuit sensing. It is designed to provide high quality and energy efficient illumination solutions. The device supports up to eight channels with tight constant current regulation and adjustable pulse width modulation (PWM) frequency.

The TLC5930PWP is available in a thermally enhanced 6mm x 6mm 32-pad QFN package. It features high-accuracy constant current regulation, up to 8 independent channels, and dimming control pin input. It also features an integrated Power Good output, Programmable Fault Timeout, and Multiple 4-bit channel configuration registers. The device is supported with a PMBus interface and various programming options.

The TLC5930PWP application field includes indoor and outdoor LED illumination, including wall washers and spotlights, LED lighting signs, LED decorative lighting, LED health lighting, LED portable lighting, LED recessed lighting, LED automotive application, LED sports lighting, LED street lighting, LED industrial and architectural lighting, LED landscape lighting, LED traffic lighting, LED stage lighting, LED task lighting, and many more.

The TLC5930PWP working principle starts when power is supplied and the device starts initializing the registers. The current control circuit senses the voltage at the output and adjusts the duty cycle of the PWM according to the programmed profile. The PWM clock and dimming control signals are adjustable with four 4-bit registers. When the voltage is increased, the duty cycle is decreased, which results in a lower output current. When the voltage is decreased, the duty cycle is increased, which results in a higher output current. The duty cycle is continuously adjusted according to the voltage, thus maintaining the output current within a tight tolerance window.

The TLC5930PWP also offers thermal protection and dimming control. When the junction temperature reaches a certain high level, the device shuts down and the output current reduces to 0mA. The dimming control signal can be used to control the output current level. It can be used to turn off the channels or to reduce the current level in multiple stepwise intervals. The thermal protection reduces the need for active cooling, allowing for smaller designs.

In addition to current regulation and thermal protection, the TLC5930PWP also offers a programmable fault timeout, a power good output, and multiple channel configuration registers. The LDOs provide easy management for the external load. The device is compact, efficient and robust, providing reliable performance with high-accuracy current regulation and tight dimming control. It is ideal for applications that require very accurate output current control, precise dimming control, and low power consumption.
