The device utilizes a boost topology with a switching frequency of 300 kHz and a maximum duty cycle of 78%. Designed for surface-mount installation, it is housed in an SOT-23-5 package. The component supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Integrated step-up switching controller designed for efficient voltage boosting applications
• Fixed output voltage configuration ensures stable power delivery without external feedback adjustments
• Compact SOT-23-5 package facilitates space-constrained circuit board layouts

Applications

• Portable electronic devices requiring compact power management solutions
• Battery-powered systems needing voltage step-up capabilities
• General-purpose DC-DC conversion circuits in consumer electronics

Procurement Notes

Verify the complete part number including suffixes against official ABLIC documentation to ensure correct voltage and package specifications. Confirm RoHS compliance status through manufacturer datasheets prior to integration. Cross-reference ordering information with authorized distributors to avoid counterfeit components. Ensure supply chain stability by checking production lead times directly with the manufacturer or certified partners.

Selection Notes

Select this component when a fixed 5.0 V output is required from a lower input voltage source. The 300 kHz switching frequency offers a balance between efficiency and external component size. Consider the 54.8 mA output current limit to ensure adequate load capacity. Verify that the SOT-23-5 package fits within the thermal and spatial constraints of the target design.

Part Context

This component belongs to the S-8357 series of switching controllers from ABLIC. The series focuses on providing reliable step-up regulation in small form factors. Similar models in the series may offer different fixed output voltages or slight variations in electrical characteristics while maintaining the same core architecture and packaging.

Replacement Considerations

Direct replacements include other S-8357 series variants with compatible pinouts and similar electrical parameters. Verify that substitute parts match the 5.0 V output requirement and 300 kHz switching frequency. Check for equivalent thermal performance and package dimensions to ensure mechanical compatibility.
