ADP8863ACBZ-R7

Overview

The ADP8863ACBZ-R7 is a seven-channel LED backlight controller manufactured by Analog Devices Inc. It utilizes a charge pump topology to drive LEDs, featuring an I2C control interface for configuration. The device operates within an input voltage range of 2.5 V to 5.5 V and supports output currents up to 60 mA per channel. It functions at a switching frequency of 1 MHz and is housed in a 20-pin WLCSP package. The component is designed for operation between -40°C and +85°C.

Feature Summary

• Integrates a charge pump circuit for efficient LED backlight driving
• Provides seven independent output channels with individual current control
• Utilizes an I2C serial interface for digital communication and configuration

Applications

• Mobile phone LCD backlight systems
• Portable electronic display illumination
• Smartphone camera flash lighting

Procurement Notes

Verify the specific suffix R7 indicates tape and reel packaging when sourcing. Confirm that the ACBZ designation corresponds to the WLCSP-20 package variant. Ensure compatibility with the target system's I2C bus voltage levels and check for any regional distribution restrictions or limited availability status prior to ordering.

Selection Notes

Select this component for applications requiring multiple LED channels controlled via a standard I2C interface. It is suitable for space-constrained designs due to its WLCSP footprint. Consider the 1 MHz switching frequency and charge pump architecture when evaluating electromagnetic interference requirements and power supply constraints for the target mobile device.
