Overview
The S-8355Q15MC-OWAT2U is a boost DC-DC switching controller from the ABLIC S-8355 series, designed for efficient voltage step-up applications. It operates within an input voltage range of 0.9V to 10V and features a fixed switching frequency of 600kHz. The device supports a maximum duty cycle of 85% and includes an enable control feature for power management. Packaged in a compact SOT-23-5 (SC-74A) surface-mount format, it is rated for operation across a temperature range of -40°C to +85°C.
Feature Summary
- Integrated boost topology for stepping up input voltages
- Fixed high-frequency switching at 600kHz for reduced passive component size
- Enable pin control for active power management and standby modes
Applications
- Battery-powered portable electronics requiring voltage boosting
- Low-voltage sensor interface circuits
- General-purpose DC-DC conversion in space-constrained PCB designs
Procurement Notes
Verify the specific suffix 'OWAT2U' against the manufacturer's official datasheet to confirm package type, marking codes, and environmental compliance status such as RoHS and REACH. Ensure that the ordering information matches the exact part number variant required for your design, as suffixes often dictate packaging and material specifications.
Selection Notes
Select this component when a boost converter with a fixed 600kHz frequency is required. It is suitable for applications needing an enable function for power control. Consider the SOT-23-5 package constraints and the 0.9V minimum input voltage requirement during schematic design. Verify compatibility with external inductor and capacitor selections based on the 85% maximum duty cycle specification.
Part Context
This part belongs to the S-8355 series of switching controllers by ABLIC Inc., which are optimized for boost converter topologies. The series is characterized by its ability to operate from low input voltages and its integration into small surface-mount packages, targeting modern consumer and industrial electronic devices where space efficiency and power management are critical.
Replacement Considerations
Consult the official ABLIC cross-reference documentation for verified substitute part numbers. Do not assume functional equivalence with other S-835x series variants without verifying electrical parameters and pinout compatibility.
