Overview
The S-8355Q33MC-OWST2U is a boost DC-DC switching controller IC manufactured by ABLIC Inc., designed for step-up voltage regulation with a positive output configuration. It operates within an input voltage range of 0.9V to 10V and delivers a fixed 3.3V output. The device features a 600kHz switching frequency and supports a maximum duty cycle of 85%. Packaged in a compact SOT-23-5 surface-mount format, it functions reliably across a temperature range of -40°C to +85°C.
Feature Summary
- Integrates a boost topology for efficient step-up voltage conversion from low input sources.
- Provides a fixed 3.3V regulated output suitable for powering downstream digital logic.
- Operates at a high 600kHz switching frequency to minimize external component size.
Applications
- Battery-powered portable electronic devices requiring voltage boosting
- Low-voltage input systems needing stable 3.3V logic supply
- Space-constrained embedded designs utilizing SOT-23-5 packaging
Procurement Notes
Verify the complete part number including suffixes against official ABLIC documentation to ensure correct output voltage and package variant. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer prior to ordering. Ensure design compatibility with the specified operating temperature range and electrical parameters.
Selection Notes
Select this component when a fixed 3.3V boost 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 are met by the external power switch, as this is a controller IC without an integrated power FET.
Part Context
This part belongs to the S-8355 series of boost controllers from ABLIC Inc. The series offers various fixed output voltages and is characterized by its wide input voltage range and small SOT-23-5 footprint. It is distinct from the S-8353 and S-8358 series which may feature different switching frequencies or control architectures.
Replacement Considerations
Direct substitutes include other parts from the S-8355 family with identical pinouts and similar electrical characteristics, such as the S-8355Q15MC-OWAT2U for different voltage outputs. Cross-referencing with other manufacturers' boost controllers requires verifying pin compatibility and switching frequency alignment.
