S-8520F27MC-BNMT2U

Overview

The S-8520F27MC-BNMT2U is a step-down switching controller manufactured by ABLIC Inc. It operates with a fixed switching frequency of 300kHz and features an input voltage range of 2.5V to 16V. The device delivers a fixed output voltage of 2.7V and maintains a typical quiescent current of 100uA. It utilizes a synchronous rectification architecture within the SOT-23-5 package, supporting an operating temperature range from -40°C to +85°C.

Feature Summary

• Synchronous rectification topology for enhanced efficiency
• Fixed 300kHz switching frequency operation
• Low quiescent current consumption

Applications

• Battery-powered portable electronics
• General-purpose DC-DC conversion stages
• Embedded system power management

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status via official documentation. Ensure storage conditions adhere to moisture sensitivity level requirements. Validate package marking against datasheet specifications to prevent counterfeit substitution during assembly.

Selection Notes

Select this component when a compact synchronous buck solution is required. The fixed 2.7V output suits logic supply rails. Verify that the 300kHz frequency aligns with electromagnetic interference constraints. Ensure input voltage remains within the specified 2.5V to 16V operational window for stable regulation.

Part Context

This part belongs to the S-8520 series of switching controllers. It shares the SOT-23-5 footprint with other variants in the family. The suffix indicates specific output voltage and packaging configuration. It serves as a core power management element in low-power applications.

Replacement Considerations

Compatible substitutes include S-8520F30MC-BNMT2U for 3.0V output and S-8520F33MC-BNMT2U for 3.3V output. These parts maintain identical pinouts and control characteristics while differing only in regulated output voltage levels.
