S-8520B27MC-ARMT2G

Overview

The S-8520B27MC-ARMT2G is a synchronous rectification step-down switching regulator manufactured by ABLIC Inc. It operates within an input voltage range of 2.5 V to 10 V and delivers a fixed output voltage of 2.7 V. The device supports a maximum output current of 1 A and features a compact HSNT-8 (2030) package measuring 3.0 mm x 2.0 mm with a maximum height of 0.5 mm. It functions across a temperature range of -40°C to +85°C, utilizing a 60 kHz switching frequency.

Feature Summary

• Integrates synchronous rectification for enhanced power conversion efficiency
• Provides high-current output capability suitable for demanding load applications
• Utilizes ultra-compact packaging to minimize printed circuit board footprint

Applications

• Power supply circuits for advanced driver assistance systems domain controllers
• Voltage regulation for industrial equipment requiring high functionality
• Battery-powered portable devices needing efficient step-down conversion

Procurement Notes

Verify the specific suffix ARMT against official ABLIC documentation to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer. Ensure design compatibility with the HSNT-8 package dimensions and thermal requirements before procurement.

Selection Notes

Select this component when a 1 A output current is required in a minimal space constraint. The fixed 2.7 V output suits logic levels requiring stable low-voltage rails. Evaluate thermal performance due to the small package size under full load conditions. Consider the 60 kHz frequency for electromagnetic interference management relative to system clock speeds.

Part Context

This part belongs to the S-8564/5 series of synchronous rectification DC-DC converters. The series is designed for applications requiring high output current in extremely small footprints. It represents ABLIC's solution for miniaturizing power management in modern electronic devices such as automotive and industrial systems.

Replacement Considerations

Direct substitutes must match the 1 A output, 2.7 V fixed voltage, and HSNT-8 package. Verify pinout compatibility and thermal characteristics. Cross-reference with other ABLIC synchronous buck regulators if pin-to-pin replacement is not feasible.
