TPS61150DRCRG4 by Texas Instruments

The TPS61150DRCRG4 is a high-performance, adjustable, dual-output, boost converter integrated circuit (IC) designed and manufactured by Texas Instruments. This IC is specifically engineered to cater to the power requirements of white LED applications and is particularly suitable for portable devices where efficient power conversion is essential.

With an input voltage range of 2.7V to 6V, the TPS61150DRCRG4 is versatile and can be powered by a variety of sources, including single-cell lithium-ion batteries. This makes it an ideal choice for battery-powered applications such as smartphones, digital cameras, and other portable electronics that require an LED backlight.

One of the key features of this product is its dual-output configuration, which allows it to drive up to six white LEDs in series with a total output voltage of up to 38V. The TPS61150DRCRG4 employs a 1.2MHz fixed-frequency PWM (Pulse Width Modulation) control to minimize ripple and eliminate the need for external frequency compensation components, thus reducing the overall solution size.

The IC also includes a built-in true-color PWM dimming controller for each output, which provides a wide range of brightness control and enhances the color accuracy of the display backlight. This dimming capability is essential for extending battery life and improving the user experience by adjusting the display brightness according to the ambient light conditions.

For safety and device protection, the TPS61150DRCRG4 incorporates over-voltage and over-temperature protection features. It also includes a soft-start mechanism that gradually increases the output voltage to prevent inrush current at startup, thereby enhancing the longevity of the LEDs and the overall system reliability.

Packaged in a compact 10-pin VSON package, the TPS61150DRCRG4 is designed for space-constrained applications. Its small footprint and high efficiency make it an excellent choice for designers looking to optimize their power management solutions in portable devices.

Overall, the TPS61150DRCRG4 is a robust, efficient, and versatile power management solution from Texas Instruments that offers high performance and reliability for a wide range of LED backlighting applications.
