ADP8860ACPZ-R7 is an LED driver integrated circuit (IC) developed by Analog Devices, Inc. It is a current-mode, pulse width modulation (PWM) LED driver that can be used to provide efficient and regulated LED lighting in designs powered by 5V or 3V regulated DC supplies. It is an ideal solution for applications that require long battery life, robust operation, and/or multiple LED strings with different drive currents.ADP8860ACPZ-R7 belongs to the family of PMIC or power management ICs. These ICs control the power consumed by a device or system and are used in power-constrained applications such as wearable and portable digital devices. It consists of a scalable PWM architecture that is optimized for driving single or multiple strings of LEDs with a wide range of brightness levels. It can drive up to eight LEDs with currents up to 20mA for each channel.The device utilizes a synchronous buck architecture which enables the supply voltage to remain in regulation. This allows for consistently high output current accuracy, regardless of the input voltage or load capacitance factors. System design is simplified with the integration of a low-ripple external filter and low-risetime voltage/current-mode control. ADP8860ACPZ-R7 also offers a selectable soft-start feature that prevents high inrush currents when the device is initially powered up. The design of the operating voltage of the device is unique compared to other PWM ICs. ADP8860ACPZ-R7 utilizes a hybrid PFM/PWM typical operating mode where the brightness control is implemented through a combination of both PFM and PWM. This hybrid mode brings a host of benefits, including making it easier to optimize the LED driver\'s efficiency, eliminating the need for any external thermal management and allowing for a smaller overall device. ADP8860ACPZ-R7 also has an integrated open LED indicator, which allows for additional safety features to be implemented in the system design. This allows for pin-point accuracy when driving multiple strings of LEDs and helps to prevent accidental damage from the LED driver.Overall, ADP8860ACPZ-R7 is a reliable, cost-effective, and efficient LED driver solution for power constrained applications. It is well-suited for applications that require multiple LED strings with different drive currents, long battery life, and robust operation.
