The SCV78663DQ1R2G is a part of the PMIC – LED Driver family. This is a cost effective, power efficient solution for managing small to medium power LED backlighting requirements. This driver is specifically designed for driving the 16 channels from a single line. It includes resources such as an on-board DC-DC converter, a current reference, over-temperature protection, kill mode support, and two boost timers for power regulation. The driver is available in two versions, a 4-bits and 8-bits resolution, so as to accommodate various customer needs.

The working principle of SCV78663DQ1R2G is based on the concept of source current control. Unlike traditional LED drivers, which provide current through a direct route, the SCV78663DQ1R2G driver uses an arrangement of source current control sections, each carrying a certain amount of current. This allows the user to create a current path pattern according to their requirements. Utilizing the mux function, 4 bits and 8 bits of LED pulse width modulation waveform can be configured.

SCV78663DQ1R2G has two main applications, one for smart phones and the other for monitor backlighting. In a smart phone application, the SCV78663DQ1R2G helps in making a smarter phone by setting up a dynamic control of the backlight brightness. This will also offer better contrast ratios, thanks to the source current control with current limit protection. For product design engineers, this means they can assign each display pixel with its own current level. Furthermore, the 8-bit resolution found in this driver makes it suitable for high-end LCD monitors, where precise color rendition and very low flicker levels are required.

As for monitor backlighting, the SCV78663DQ1R2G can be used to provide a unique experience in backlight intensity control. Utilizing the DC-DC converter, this driver provides an efficient power saving solution allowing lower operating costs, while still preserving the backlight’s uniformity. Moreover, the over-temperature protection and the kill mode support provides an added layer of safety for visually-intensive applications. This can be useful for motion graphics and gaming projects where bright, vivid colors and sharp images are required.

In conclusion, the SCV78663DQ1R2G driver is an economic, power efficient, and multi-faceted solution for small to medium LED backlighting applications. With its source current control, 4-bits and 8-bits resolution, one-line 16-channel control, on-board DC-DC converter, current reference, over-temperature protection, kill mode support, and two boost timers, the SCV78663DQ1R2G offers a high level of customization that is unmatched in the LED driver market.
