TheTPS60231RGTRG4 is a highly integrated, high-performance Power Management Integrated Circuit (PMIC) specifically designed for Red/Green/Blue (RGB) Light-Emitting Diode (LED) driving applications. It features wide input voltage range from 4V to 42V, low voltage shutdown (0.6V), and pulse-width modulation (PWM) dimming capability with a PWM frequency range of 100kHz to 1MHz. This PMIC integrates a boost controller operating up to 42V and up to 95% efficiency to supply its internal circuitry, allowing the LED to be powered directly from the input battery.In LED driver applications, theTPS60231RGTRG4 is designed to be used in conjunction with a microcontroller. It can be controlled by programming the appropriate registers in the microcontroller while monitoring the LED driving signals. An internal device interrupt is used to indicate system condition changes from the microcontroller. This feature allows users to monitor and control system status in a timely basis.For optimal energy efficiency, theTPS60231RGTRG4 features an adjustable output current limit. This current limit is used to maintain a constant output current over a wide range of input voltages and can be set to any desired value between 16mA and 1.3A. The current limit reduces power losses and improves thermal performance, allowing higher load currents without the need of a higher voltage input supply.TheTPS60231RGTRG4 also integrates a switched-mode boost converter operating up to 42V and up to 95% efficiency. This voltage regulator can be programmed to output a fixed voltage or triggered by a GPIO pin. Its high-frequency switch of 300kHz offers improved system footprint and total component count for a space-saving design. The narrow switching frequency allows an unorbited inductor size with minimized EMI.TheTPS60231RGTRG4 utilizes Adaptive Skip Mode for improved light-load efficiency. When the LED current is reduced to a certain threshold, the boost controller automatically enters skip mode. This feature helps reduce total power dissipation and increases system efficiency.For complete protection, theTPS60231RGTRG4 integrates several analog and digital functions, such as programmable over-current and over-voltage protection, under-voltage lockout, and thermal regulation systems. These safety features protect against abnormal device operation or component failure, ensuring reliable operation and long battery life.For a green LED driving applications, theTPS60231RGTRG4 supports an advanced pulse-width modulation (PWM) dimming mode. The PWM dim controller provides high linearity low noise modulated input with a PWM frequency range of 100kHz to 1MHz. The dim controller can be adjusted through the registers in the microcontroller for optimal dimming under varying ambient conditions.In short, theTPS60231RGTRG4 is an ideal solution for all types of RGB LED driving applications, providing a low voltage solution with excellent performance, efficiency, and protection features. The integration of all these features reduces component count and design time, making it the perfect choice for optimizing power and cost performance.
