Overview
The ADP1882ARMZ-0.6-R7 is a synchronous current-mode Buck switching controller from Analog Devices, designed for high-efficiency power conversion. It features a fixed 600 kHz switching frequency and supports an output voltage of 800 mV with a maximum output current capability of 25 A. The device operates within a supply voltage range of 3 V to 20 V and includes a shutdown function for power management. It is housed in a 10-MSOP surface-mount package and functions across an extended temperature range from -40°C to +125°C.
Feature Summary
- Synchronous current-mode control architecture with constant on-time PWM regulation
- Integrated enable pin for precise power sequencing and shutdown control
- Optimized for high efficiency in step-down DC-DC converter applications
Applications
- Point-of-load (POL) voltage regulation modules
- High-density server and workstation power supplies
- Industrial equipment power distribution systems
Procurement Notes
Verify the specific suffix '0.6' confirms the 600 kHz switching frequency variant when sourcing. Ensure the MSOP-10 package matches your PCB footprint requirements. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Cross-reference the full part number against Analog Devices catalogs to avoid confusion with other frequency options in the ADP1882 series.
Selection Notes
Select this component for designs requiring a fixed 600 kHz switching frequency to balance size and efficiency. The 25 A current capability suits moderate-to-high load applications. Consider the 800 mV minimum output voltage constraint for low-voltage digital core supplies. The 10-MSOP package offers a compact solution for space-constrained layouts compared to larger packages.
Part Context
This part belongs to the ADP1882 family of synchronous Buck controllers. Variants such as ADP1882ARMZ-1.0-R7 offer different switching frequencies like 1 MHz. The family shares common architectural features including current-mode control and integrated drivers, but differs in switching speed and associated passive component selection requirements.
Replacement Considerations
Direct substitutes include other ADP1882 variants with adjusted switching frequencies, such as ADP1882ARMZ-1.0-R7. Verify that alternative components support the required 600 kHz operation or allow for redesigning the compensation network and inductor values accordingly.
