Overview
The ADP5310AREZN-255R7 is a power management unit integrating dual adjustable buck regulators and one load switch within a 16-lead TSSOP_EP package. It provides three outputs: two regulated rails and one switched rail. The fixed output voltage for the second regulator is specified as 2.55V. Current capabilities are 50mA, 300mA, and 800mA across the outputs. The device operates over an extended temperature range of -40°C to 125°C.
Feature Summary
- Integrates dual buck converters and a load switch into a single compact package
- Designed to meet demanding performance requirements while minimizing board space
- Provides flexible power delivery with adjustable and fixed output options
Applications
- Portable electronic devices requiring efficient power management
- Systems needing multiple voltage rails from a single component
- Battery-powered applications utilizing low-power buck regulation
Procurement Notes
Verify the specific suffix R7 indicates reel packaging when ordering. Confirm the 2.55V fixed output requirement matches the design specification, as other variants may offer different fixed voltages or fully adjustable ranges. Ensure the 16-TSSOP_EP footprint aligns with the PCB layout constraints before finalizing procurement.
Selection Notes
Select this component when board real estate is limited and multiple power domains are required. The integrated load switch simplifies sequencing compared to discrete solutions. Verify that the 800mA peak current capability meets the transient load demands of the target application without exceeding thermal limits in the TSSOP_EP package.
Part Context
This part belongs to the ADP5310 family of ultra-low power PMICs from Analog Devices. It is distinct from similar models like the ADP5304 by its specific integration of dual buck regulators and a load switch. The AREZN-255R7 variant specifically denotes the 2.55V fixed output configuration and reel packaging format.
Replacement Considerations
The ADP5304ACPZ-2-R7 is listed as a related alternative in public documentation. Verify pin compatibility and output current specifications before substitution, as functional differences may exist between the ADP5304 and ADP5310 series.
