S-8520C30MC-BRPT2G

Overview

The S-8520C30MC-BRPT2G is a synchronous rectification switching regulator IC manufactured by ABLIC Inc. It operates with an input voltage range of 2.5V to 16V and provides a fixed output voltage of 3.0V. The device features a switching frequency of 180kHz and supports up to 100% duty cycle operation. It is housed in a compact SOT-23-5 package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates synchronous rectification for improved efficiency
• Supports 100% duty cycle operation for low dropout performance
• Includes enable control functionality

Applications

• Portable electronic devices requiring efficient power conversion
• Battery-powered systems utilizing single-cell lithium-ion or polymer sources
• Embedded applications with strict space constraints

Procurement Notes

Verify the specific suffix BRPT2G against official ABLIC documentation to confirm pinout, marking codes, and tape-and-reel specifications. Ensure compatibility with your PCB footprint and reflow profile requirements before finalizing procurement orders.

Selection Notes

Select this component when a synchronous buck topology is required for higher efficiency compared to asynchronous alternatives. The fixed 3.0V output suits logic supply rails, while the wide input range accommodates varying battery states.

Part Context

This part belongs to the S-8520 series of DC-DC switching controllers from ABLIC. The series is characterized by its integration of synchronous rectification drivers and support for high-efficiency step-down conversion in small surface-mount packages suitable for modern portable electronics.

Replacement Considerations

Consult official substitution lists for equivalent synchronous buck regulators. Verify that any alternative maintains the 180kHz switching frequency, SOT-23-5 package dimensions, and 3.0V output accuracy.
