S-8521D36MC-BXVT2U

Overview

The S-8521D36MC-BXVT2U is a synchronous rectification step-down switching regulator IC manufactured by ABLIC Inc. It operates within an input voltage range of 2.5V to 16V and provides a fixed output voltage of 3.6V. The device supports a maximum output current of 1A and features a switch frequency of 60kHz. It utilizes a SOT-23-5 package and functions across a temperature range of -40°C to +85°C.

Feature Summary

• Synchronous rectification topology for improved efficiency
• Built-in power good function for system monitoring
• Fixed output voltage configuration
• Compact surface-mount packaging

Applications

• Portable electronic devices requiring efficient power conversion
• Battery-powered equipment with limited space constraints
• General-purpose DC-DC conversion in consumer electronics

Procurement Notes

Verify the specific suffix BXVT2U against official ABLIC documentation to confirm exact marking and tape/reel specifications. Ensure compatibility with existing PCB footprints for the SOT-23-5 package. Confirm availability status as distribution data may vary by region.

Selection Notes

Select this component when a compact, high-efficiency buck converter is required for low-to-medium current applications. The fixed 3.6V output simplifies design compared to adjustable variants. Verify that the 1A current rating meets load requirements and that the 60kHz frequency aligns with EMI constraints.

Part Context

This part belongs to the S-8521 series of synchronous rectification switching regulators from ABLIC. The series is designed for applications demanding high efficiency and small form factors. The S-8521D36 variant specifically targets systems needing a stable 3.6V supply from higher input voltages.

Replacement Considerations

Check for direct pin-compatible alternatives within the S-8521 family with different output voltages or current ratings. Verify if other manufacturers offer synchronous buck converters with similar 1A output and 16V max input specifications.
