S-8355Q60MC-OXTT2U

Overview

The S-8355Q60MC-OXTT2U is a positive output boost DC-DC switching controller IC manufactured by ABLIC Inc. It operates with a fixed switching frequency of 600kHz and supports a maximum duty cycle of 85%. The device functions within an input voltage range of 0.9V to 10V and delivers a regulated output voltage of 6.0V. It utilizes a single-output configuration housed in a compact SOT-23-5 package. The component is designed for surface-mount installation and maintains operational reliability across a temperature range of -40°C to +85°C.

Feature Summary

• Integrated step-up topology for efficient voltage elevation from low input sources
• Fixed high-frequency operation enabling the use of small external passive components
• Wide input voltage capability supporting direct connection to various power sources

Applications

• Battery-powered portable electronic devices requiring voltage boosting
• Low-voltage sensor interfaces needing stable higher supply rails

Procurement Notes

Verify the complete part number including suffixes against official manufacturer documentation to ensure correct output voltage and package variant. Confirm RoHS compliance status and environmental declarations prior to integration. Cross-reference datasheet revisions to validate pinout and electrical characteristics match current design requirements.

Selection Notes

Select this component when a fixed 6.0V output is required from inputs as low as 0.9V. The 600kHz frequency allows for smaller inductors compared to lower-frequency alternatives. Ensure the application load current remains within the controller's driver capabilities and that thermal constraints in the SOT-23-5 package are respected during operation.

Part Context

This part belongs to the ABLIC S-8355 series, which comprises boost switching controllers designed for space-constrained applications. The series offers various fixed output voltages to suit different system requirements while maintaining a consistent footprint and control interface architecture across the family.

Replacement Considerations

Compatible substitutes include other S-8355 series variants with different fixed output voltages, such as S-8355Q33MC or S-8355Q50MC, provided the specific output level matches the circuit design needs.
