S-8357G33MC-MIST2G

Overview

The S-8357G33MC-MIST2G is a step-up switching regulator controller manufactured by ABLIC Inc. It operates in the Boost topology with a single output configured for a fixed voltage of 3.3 V. The device supports an output current capability of 38.5 mA and functions at a switching frequency of 300 kHz. It features a maximum duty cycle of 78%. The component is designed for surface mount installation in an SOT-23-5 package. It is rated for operation within a temperature range from -40°C to +85°C.

Feature Summary

• Integrated step-up switching regulator controller optimized for compact power management applications
• Fixed output voltage configuration ensuring stable power delivery without external feedback adjustments
• High-frequency switching operation enabling the use of small passive components

Applications

• Portable electronic devices requiring efficient battery voltage boosting
• Low-power sensor nodes needing regulated supply rails
• Compact industrial control modules operating within standard temperature ranges

Procurement Notes

Verify the specific suffix 'MIST2G' against official ABLIC documentation to confirm exact tape-and-reel specifications and marking codes. Ensure compatibility with existing PCB footprints for the SOT-23-5 package. Cross-reference the RoHS compliance status directly with the manufacturer's latest environmental declaration before finalizing procurement orders.

Selection Notes

Select this component when a fixed 3.3 V boost output is required with moderate current demands up to 38.5 mA. The 300 kHz switching frequency allows for smaller inductors compared to lower-frequency alternatives. Verify that the input voltage range supports the intended source, as the datasheet specifies minimum operating conditions. Consider thermal dissipation requirements given the small SOT-23-5 package size under load.

Part Context

This part belongs to the S-8357 series of switching regulators from ABLIC Inc., designed for general-purpose power management. The series offers various fixed output voltages and packaging options to suit different space-constrained designs. As a controller-based solution, it requires external power switches and passive components, providing flexibility in circuit design while maintaining high efficiency.

Replacement Considerations

Direct replacements include other S-8357 series variants with identical pinouts and similar electrical characteristics, such as the S-8357F33MC-MGST2U or S-8357B48UA-NJHT2G, provided the output voltage and current ratings meet application needs. Verify package compatibility and thermal performance before substitution.
