ADP8861ACPZ-RL is a high performance Power Management Integrated-Circuit (PMIC) designed for LED drivers. It has built-in controllers and Power Management Units (PMU), which significantly reduce the number of components required for LED applications and simplify the development process. This PMIC is ideal for applications such as general LED lighting, LED displays, and signal indicators.

The ADP8861ACPZ-RL features an advanced on-die Power Management Unit (PMU) for digital control of the LED drivers. This PMU allows for programmable features, such as LED dimming, over-temperature protection, and more. Additionally, the ADP8861ACPZ-RL includes digital control of up to 16 LED strings. With this feature, designers can create LED products with many combinations of LED string level brightness and color while optimizing their total current.

The ADP8861ACPZ-RL also features built-in lighting sequencers, designed to save development time and costs by providing the ability to create complex lighting schemes with minimal coding. Additionally, the device also provides a wide range of protection features, including over-voltage, under-voltage, over-temperature, and short-circuit protection.

The working principle of the ADP8861ACPZ-RL PMIC is relatively simple. It combines a DC/DC controller and switching regulators with three adaptive control loops, which are used to control the output voltage and current. The DC/DC controller adjusts the output voltage, while the adaptive control loops adjust the switching frequency and average current, resulting in a stable output voltage, even under heavy loads. The device also includes a number of digital control functions, such as LED string control, dimming control, and more.

Though its features are complex, the ADP8861ACPZ-RL is not difficult to use. The on-die PMU simplifies the development process, while the built-in lighting sequencer makes it easy to create complex lighting schemes. Additionally, the device’s protection features help ensure that LED systems operate safely and reliably. With these features, the ADP8861ACPZ-RL is an ideal PMIC solution for LED drivers.
