S-8357F30MC-MGPT2G

Overview

The S-8357F30MC-MGPT2G is a step-up switching controller from the ABLIC S-8357 series, designed for boost topology applications. It provides a fixed output voltage of 3.0 V with a high accuracy of ±2.4%. The device operates with a switching frequency of 300 kHz and delivers an output current capability of 46.9 mA. It functions within a wide input voltage range up to 10 V and supports operation temperatures from -40°C to +85°C. Packaged in a compact SOT-23-5 format, it integrates internal components to minimize external part count.

Feature Summary

• Integrates a power MOSFET and control circuitry into a single compact package to reduce external component requirements.
• Features a fixed output voltage option with high precision regulation to ensure stable power delivery.
• Supports continuous step-up conversion using a boost topology for efficient voltage elevation.

Applications

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

Procurement Notes

Verify the specific suffix MGPT2G against the official ABLIC datasheet to confirm pinout and marking codes. Ensure the ordering quantity aligns with manufacturer reel specifications. Cross-reference the RoHS compliance status directly with the latest product documentation before finalizing procurement.

Selection Notes

Select this model when a fixed 3.0 V output is required without external resistor programming. The 300 kHz frequency allows for smaller passive components compared to lower-frequency alternatives. Verify that the load current does not exceed the specified 46.9 mA limit under all operating conditions.

Part Context

This component belongs to the S-8357 series of switching controllers, which are optimized for space-constrained designs. The series utilizes CMOS technology to achieve low standby current and high efficiency. It serves as a direct replacement for older discrete boost solutions in portable electronics.

Replacement Considerations

Check for S-8357F30MC-MGST2U or similar variants within the same series for potential pin-compatible alternatives. Confirm that any substitute maintains the identical 3.0 V output and SOT-23-5 footprint.
