Overview

The S-8355Q28MC-OWNT2G is a CMOS step-up switching regulator manufactured by ABLIC Inc. It operates with an input voltage range of 0.9V to 10V and provides a fixed output voltage of 2.8V. The device features a switching frequency of 600kHz and a maximum duty cycle of 85%. Quiescent current is specified at 25.9uA. It is housed in an SOT-23-5 package suitable for surface mount applications.

Feature Summary

• CMOS step-up switching regulator controller architecture
• Integrated reference voltage source and oscillation circuit
• High switching frequency operation for compact external components

Applications

• Battery-powered portable devices requiring voltage boosting
• Low-voltage power supply systems
• General-purpose DC-DC conversion in consumer electronics

Procurement Notes

Verify the specific suffix 'OWNT2G' against official ABLIC documentation to confirm package type, tape-and-reel specifications, and environmental compliance status. Ensure compatibility with existing PCB footprint and soldering profiles before finalizing procurement orders.

Selection Notes

Select this component when a fixed 2.8V output is required from inputs as low as 0.9V. The 600kHz frequency allows for smaller inductors compared to lower-frequency alternatives. Verify that the load current requirements do not exceed the internal switch capabilities defined in the datasheet.

Part Context

This part belongs to the S-8355/56/57/58 series of switching regulators. These are designed using CMOS process technology to achieve high efficiency and low current consumption. The series is intended for applications requiring reliable step-up conversion in space-constrained environments.

Replacement Considerations

Check for parts within the S-8355 series with different output voltages or packages if exact pinout matches are unavailable. Cross-reference electrical parameters such as quiescent current and switching frequency to ensure functional equivalence.
