S-8357G32MC-MIRT2G

Overview

The S-8357G32MC-MIRT2G is a step-up switching regulator controller manufactured by ABLIC Inc. It operates within an input voltage range of 0.9V to 10V and delivers a fixed output voltage of 3.2V. The device features a switch current capacity of 25.9uA and operates at a switching frequency of 300 kHz. It utilizes PWM control with a maximum duty cycle of 78%. The component is housed in an SOT-23-5 package, supports surface mount installation, and functions reliably across a temperature range of -40°C to +85°C.

Feature Summary

• Integrates PWM-based step-up regulation for efficient voltage boosting
• Supports wide input voltage ranges from low battery levels up to 10V
• Operates with high switching frequency for compact external component sizing

Applications

• Battery-powered portable electronic devices requiring voltage boosting
• Low-voltage power supply systems needing stable 3.2V output
• Embedded circuits operating within industrial temperature environments

Procurement Notes

Verify the complete part number including suffixes against official ABLIC documentation to ensure correct package and tape/reel specifications. Confirm RoHS compliance status through manufacturer datasheets prior to integration. Cross-reference ordering codes with authorized distributors to avoid counterfeit components. Ensure design compatibility with required thermal management for the SOT-23-5 package.

Selection Notes

Select this component when a fixed 3.2V output is required from inputs between 0.9V and 10V. The 300kHz switching frequency allows for smaller inductors compared to lower-frequency alternatives. Verify that the load current requirements do not exceed the internal switch limits. Consider the SOT-23-5 footprint constraints during PCB layout planning.

Part Context

This device belongs to the S-8357 series of switching controllers from ABLIC Inc. The series focuses on step-up topologies suitable for portable applications. The specific model indicates a 3.2V fixed output variant packaged in SOT-23-5. It is categorized under PMIC switching controllers designed for efficient power management in small form factors.

Replacement Considerations

Direct substitutes include other S-8357 series variants with compatible output voltages such as S-8357F50MC-MHJT2U or S-8357B48UA-NJHT2G, provided pinout and electrical parameters match the design requirements. Verify package compatibility before substitution.
