The TPS61150ADRCT is a PMIC—LED Drivers component that is versatile, efficient, and highly efficient for a variety of lighting applications. The device is designed to provide high efficiency, low current consumption, high switching frequency, and low thermal dissipation. The TPS61150ADRCT operates from an input voltage range from 4.5 V to 20 V, and is capable of providing regulated output currents from 200 uA to 1 A depending on the number of LEDs connected.

The TPS61150ADRCT is a constant current LED driver. It includes a Fixed Frequency Step-Down LED Driver and an Internal Low Side Slope Compensation. The internal voltage regulation prevents LED flickering, even when the power supply voltage has some fluctuations. The TPS61150ADRCT is optimized for white LED configuration, but can operate LEDs of other colors as well. The TPS61150ADRCT is available in a small 2 mm x 2 mm WLCSP (Wafer Level Chip Scale Package).

The TPS61150ADRCT is designed to be used in a wide range of applications, including automotive, consumer electronics, general purpose, outdoor, and medical lighting. It is suitable for driving single- or multi-LED strings and AC/DC-type luminaries. The TPS61150ADRCT features a low start up current, an adjustable current limit, short circuit protection, and over temperature protection. It also has an adjustable dimming of up to 99% for constant current output, and supports a wide range of dimming approaches such as PWM dimming, analog and digital dimming.

The TPS61150ADRCT operates in low ripple constant current (LRC) mode and the output current is regulated by the duty cycle of the Pin0 signal. When the signal is driven instead of a resistive divider, the constant current output is signed with a dynamic, adjustable current limit. The TPS61150ADRCT also has an adjustable soft start mode allowing the current to ramp up slowly when the power is turned on or when switching between dimming modes.

In summary, the TPS61150ADRCT is an efficient, low power consumption LED driver for a variety of lighting applications, particularly for white LEDs. It is designed for single LED string, dimmable LED strings and AC/DC-type lighting systems, and features adjustable current limit, short circuit protection, and over temperature protection. It also has an adjustable dimming of up to 99% for constant current output, and supports a wide range of dimming approaches such as PWM dimming, analog, and digital dimming.
