ADP8866ACPZ-R7

Overview

The ADP8866ACPZ-R7 is a nine-channel LED driver IC manufactured by Analog Devices Inc., housed in an LFCSP-20 package. It utilizes a charge pump topology to drive LEDs with a maximum output current of 25 mA per channel. The device operates on an input voltage range of 2.5 V to 5.5 V and generates an output voltage between 4.3 V and 5.5 V. It features I2C control, a switching frequency of 1 MHz, and functions within a temperature range of -40°C to +105°C.

Feature Summary

• Integrates a charge pump for efficient LED driving
• Provides nine independent output channels
• Supports digital configuration via I2C interface

Applications

• LED backlighting systems
• Indicator lighting circuits
• Portable electronic displays

Procurement Notes

Verify the specific suffix R7 indicates reel packaging when ordering. Confirm the LFCSP-20 package type matches your PCB footprint requirements. Ensure the I2C address configuration aligns with your system design. Check for moisture sensitivity handling instructions during storage and assembly.

Selection Notes

Select this component when multiple low-current LED channels require individual control. The integrated charge pump eliminates external inductors compared to buck converters. Verify that the 25 mA per channel limit meets your brightness requirements. Ensure the 1 MHz switching frequency fits your EMI constraints.

Part Context

This part belongs to the ADP8866 series of LED drivers from Analog Devices. It is designed for applications requiring compact solutions with multiple LED outputs. The LFCSP-20 package offers a small form factor suitable for space-constrained designs.

Replacement Considerations

Consult official documentation for direct pin-to-pin replacements. Cross-reference specifications such as output current and voltage ranges before substituting.
