Overview
The ADP1877ACPZ-R7 is a dual-output synchronous step-down DC-to-DC controller manufactured by Analog Devices. It operates within an input voltage range of 2.5 V to 5.5 V and provides adjustable output voltages from 600 mV to 13.05 V with a maximum output current of 30 A per channel. The device functions at switching frequencies up to 1 MHz and supports operation temperatures between -40°C and +85°C. Packaged in a 32-lead LFCSP, it integrates features such as I2C control for configuration and monitoring.
Feature Summary
- Dual-channel synchronous buck architecture for independent power rail generation
- I2C interface enabling digital control, programming, and real-time status monitoring
- High-efficiency synchronous rectification design optimized for low thermal dissipation
Applications
- Xbox 360S console power management systems
- Multi-rail server and storage subsystems requiring synchronized buck conversion
- Industrial equipment needing isolated or coupled dual-voltage regulation
Procurement Notes
Verify the specific suffix R7 indicates reel packaging when sourcing. Confirm the LFCSP-32 package variant matches your PCB footprint requirements. Ensure compatibility with the required I2C address settings for system integration. Check for any recent product discontinuance notices from Analog Devices regarding this specific part number revision.
Selection Notes
Select this component when dual independent outputs are required from a single controller unit. The 30 A current capability suits high-power load applications. Verify that the 1 MHz switching frequency aligns with your electromagnetic interference constraints. Ensure the I2C bus speed supports your system's communication latency requirements.
Part Context
This part belongs to the ADP1877 family of synchronous buck controllers. It is designed for applications requiring two regulated outputs from a common input source. The LFCSP-32 package facilitates compact board layouts. It serves as a core power management element in complex electronic systems requiring efficient voltage translation.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Consult Analog Devices technical support for direct pin-compatible alternatives if this component is discontinued or unavailable.
