S-8521A27MC-AXMT2G

Overview

The S-8521A27MC-AXMT2G is a buck DC-DC switching controller manufactured by ABLIC Inc. It operates with a fixed switching frequency of 60kHz and supports a duty cycle up to 100%. The device features a positive output configuration and includes an enable control function. It is designed for surface-mount installation in SC-74A (SOT-753) packages, specifically SOT-23-5. The controller requires a supply voltage range of 2.5V to 10V and functions within a temperature range of -40°C to +85°C.

Feature Summary

Integrated buck topology controller for step-down DC-DC conversion applications
Fixed internal switching frequency operation at 60kHz for consistent performance
Supports 100% maximum duty cycle capability for low dropout operation
Includes enable pin functionality for power management control

Applications

Step-down DC-DC converter circuit design
Portable electronic device power regulation
Embedded system voltage stepping

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm package marking matches the specific suffix AXMT2G. Check RoHS compliance status against current environmental regulations. Ensure storage conditions maintain moisture sensitivity level 1 integrity prior to soldering.

Selection Notes

Select this component when a fixed-frequency buck controller is required without external synchronization needs. The 60kHz frequency suits applications where moderate switching speed balances efficiency and EMI constraints. Verify that the 2.5V to 10V Vcc range aligns with the system's available logic or auxiliary power rails.

Part Context

This part belongs to the S-8521 series of switching controllers from ABLIC Inc., designed for efficient power management in compact form factors. The series utilizes standard surface-mount packaging to facilitate automated assembly processes in consumer and industrial electronics manufacturing lines.
