S-8357N53MC-O3MT2G

Overview

The S-8357N53MC-O3MT2G is a positive output step-up DC-DC controller IC manufactured by ABLIC Inc. It operates within an input voltage range of 900 mV to 10 V and provides a fixed output voltage of 5.3 V. The device supports a maximum output current of 282 mA and features a low quiescent current of 31 uA. It functions at a switching frequency of 250 kHz and is housed in a compact SC-74A (SOT-753) surface-mount package. The component is rated for operation between -40°C and +85°C.

Feature Summary

• Integrated boost regulator controller with enable control feature
• Fixed 5.3 V output voltage configuration
• Compact SC-74A surface-mount packaging

Applications

• Portable electronic devices requiring step-up voltage conversion
• Battery-powered systems needing regulated 5.3 V supply
• General purpose DC-DC power management circuits

Procurement Notes

Verify the exact part number S-8357N53MC-O3MT2G against official ABLIC documentation to confirm pinout compatibility and electrical specifications. Ensure the supplier provides valid RoHS compliance certificates. Cross-reference the manufacturer date code and lot traceability to guarantee component authenticity and quality standards before finalizing procurement orders.

Selection Notes

Select this component when a fixed 5.3 V output is required from a variable or lower input voltage source. The 250 kHz switching frequency allows for smaller external passive components compared to lower-frequency alternatives. Consider the 31 uA quiescent current for battery life optimization in standby modes. Verify that the SC-74A package fits the available PCB real estate constraints.

Part Context

This part belongs to the S-8357 series of boost regulators from ABLIC. It is designed as a standalone controller, requiring external power switches and inductors. The series targets applications demanding efficient step-up conversion in space-constrained environments. The specific suffix indicates the fixed output voltage and package type variations within the broader product family.

Replacement Considerations

Direct substitutes must match the 5.3 V fixed output, 250 kHz frequency, and SC-74A package. Verify equivalent input voltage ranges and output current capabilities. Check for compatible enable logic levels and thermal performance characteristics to ensure seamless integration without circuit redesign.
