Overview
The ADP8861ACBZ-R7 is a charge pump-based LED backlight controller manufactured by Analog Devices Inc. It features seven independent output channels, each capable of delivering up to 60 mA. The device operates within an input voltage range of 2.5 V to 5.5 V and supports I2C control for configuration. It utilizes a 1 MHz switching frequency and provides an output voltage range of 4.3 V to 5.5 V. The component is housed in a WLCSP-20 package and functions reliably across a temperature range of -40°C to +85°C.
Feature Summary
- Integrates seven independent current-regulated outputs for multi-zone LED driving
- Utilizes charge pump topology to boost voltage for series LED strings
- Enables digital configuration and monitoring via standard I2C interface
Applications
- Mobile phone LCD backlight systems
- Portable electronic display illumination
- Camera flash driver circuits
Procurement Notes
Verify the specific suffix R7 indicates reel packaging when sourcing. Confirm the ACBZ designation matches the required WLCSP-20 footprint and thermal characteristics. Ensure the operating environment stays within the specified -40°C to +85°C range. Check for RoHS compliance documentation if required by your manufacturing standards. Validate supply chain availability as distribution status may vary.
Selection Notes
Select this component when designing systems requiring multiple independently controlled LED zones from a single IC. It is suitable for applications needing high efficiency with minimal external components due to the integrated charge pump. Consider the WLCSP-20 package size constraints during PCB layout. Ensure the host processor supports the necessary I2C communication protocol for control.
Part Context
This part belongs to the ADP8861 family of LED drivers designed for portable electronics. It shares functional similarities with the ADP8860 but differs primarily in its WLCSP-20 packaging compared to the LFCSP-20 variant. Both devices offer seven-channel output capabilities for backlighting applications.
Replacement Considerations
The ADP8860ACPZ-R7 serves as a direct functional alternative with identical electrical specifications, differing only in the LFCSP-20 package instead of WLCSP-20.
