The ADP8861ACBZ-R7 is an advanced PMIC (Power Management Integrated Circuit) solution specifically designed for the control of high-power central light source, or multiplexed string LEDs. It is specifically designed to help facilitate the integration of high power LEDs into various lighting applications, and can be used in a wide variety of applications, from small-scale spot lighting to large-scale home and office lighting.

The ADP8861ACBZ-R7 supports the high-side drive of a single central bright light source, allowing the LED light to be dimmed over a much wider range than is possible with conventional LED drivers. This makes the device suitable for applications where precise levels of dimming are desired. It can also be used to drive multiple LED strings, enabling high flexibility in terms of light source configuration. Additionally, the ADP8861ACBZ-R7 can be used to power two or more LED strings directly, allowing incredibly precise levels of dimming control.

The ADP8861ACBZ-R7 utilizes two fully independent channels, making it an ideal solution for applications requiring simultaneous, yet independent, control over two or more LED strings. Each of the two channels supports up to seven strings with series current limit, supporting up to 3A of output current per channel. The device supports many other features as well, such as a programmable low-voltage start, power save mode and a maximum backvoltage limit. In addition, the integrated forward voltage compensation feature helps to prevent over-dimming of LEDs.

In terms of its working principle, the ADP8861ACBZ-R7 utilizes an advanced PWM (pulse width modulation) modulation scheme that allows it to produce a constant PWM current waveform, which drives the LEDs. Each channel is driven by its own independent PWM signal, which can be programmed through the I2C or I/O interface. The device supports various control signals, including analog, digital and pulse-width modulation. The varying pulse width of the PWM signals allow for precise levels of dimming across each channel, providing a wide range of dimming levels with minimal power consumption.

The ADP8861ACBZ-R7 can be used in a wide variety of LED-based applications, ranging from small-scale spot lighting up to large-scale home and office lighting. The wide range of dimming levels offered, as well as its ability to drive multiple LED strings, make it an ideal solution for a variety of LED lighting applications. It is also a great solution for OEMs looking for an advanced and highly efficient LED driver.
