S-8357H30MC-NMPT2U

Overview

The S-8357H30MC-NMPT2U is a step-up switching controller manufactured by ABLIC Inc. It operates with a fixed switching frequency of 300 kHz and supports a maximum duty cycle of 78%. The device provides a regulated output voltage of 3 V with an output current capability of 38.5 mA. It functions within a temperature range from -40 °C to +85 °C and utilizes an SOT-23-5 surface-mount package.

Feature Summary

• Integrated boost topology for efficient voltage step-up conversion
• Fixed high-frequency operation to minimize external component size
• Compact five-pin surface-mount packaging for space-constrained designs

Applications

• Portable electronic devices requiring battery voltage boosting
• Low-power sensor nodes needing stable supply rails
• Battery-operated instrumentation systems

Procurement Notes

Verify the specific suffix NMPT against official ABLIC documentation to confirm tape-and-reel specifications and marking codes. Ensure compatibility with standard SOT-23-5 footprints during PCB layout. Cross-reference the full part number with manufacturer databases to validate current availability status and lead times before finalizing procurement plans.

Selection Notes

Select this component when a compact, fixed-frequency boost solution is required for low-current applications. The 300 kHz frequency allows for smaller inductors compared to lower-frequency alternatives. Verify that the 38.5 mA output current meets the load requirements and that the 3 V output aligns with the target system voltage needs.

Part Context

This part belongs to the S-8357 series of switching controllers from ABLIC. The series focuses on providing efficient power management solutions in small packages. The H30 designation indicates the specific 3 V output variant within this family, designed for applications requiring precise voltage regulation from single-cell sources.

Replacement Considerations

Direct replacements include other S-8357 series variants with matching output voltages and pinouts, such as the S-8357F33MC-MGST2U if a 3.3 V output is acceptable. Verify electrical parameters and package dimensions before substitution.
