Overview
The ADP8861ACPZ-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 is housed in a 20-lead LFCSP package. The component functions reliably across an operating temperature range from -40°C to +85°C.
Feature Summary
- Integrates seven independent high-side current sources for multi-zone LED driving
- Employs a charge pump topology to generate necessary boost voltage for LED strings
- Provides digital interface control via standard I2C communication protocol
Applications
- Mobile phone LCD backlight systems
- Portable electronic device display illumination
- Multi-zone LED lighting control circuits
Procurement Notes
Verify the specific suffix R7 indicates reel packaging when sourcing. Confirm the LFCSP-20 package dimensions match your PCB footprint requirements. Check RoHS compliance status through official manufacturer documentation before integration. Ensure supply chain availability aligns with production schedules as distribution may vary.
Selection Notes
Select this component when designing systems requiring multiple independently controlled LED zones. It is suitable for applications needing precise current regulation without external sense resistors. Consider the 2.5 V to 5.5 V input range compatibility with system power rails. Evaluate the 1 MHz frequency for EMI management against other available controllers.
Part Context
This part belongs to the ADP886x series of LED drivers designed for portable electronics. It shares functional similarities with the ADP8860 but offers specific channel configurations tailored for complex display backlights. The series emphasizes compact form factors and efficient power management for battery-operated devices.
Replacement Considerations
The ADP8860ACPZ-R7 is a related variant within the same family. Verify pin-to-pin compatibility and specific feature differences such as current limits or control interfaces before substitution. Consult official datasheets to ensure electrical parameters meet design requirements.
