S-8352C33UA-K6ST2G

Overview

The S-8352C33UA-K6ST2G is a positive output step-up DC-DC switching controller IC manufactured by ABLIC Inc. It operates within an input voltage range of 900 mV to 10 V and provides a fixed output voltage of 3.3 V. The device supports an output current of up to 231 mA with a typical quiescent current of 23.2 uA. It functions at a switching frequency of 100 kHz and utilizes PFM control for efficiency. The component is housed in a compact SOT-89-3 package, suitable for surface mount applications across a temperature range of -40°C to +85°C.

Feature Summary

• Integrates a boost switching regulator controller optimized for low power consumption
• Utilizes Pulse Frequency Modulation (PFM) control scheme for enhanced efficiency
• Designed for single-output positive voltage step-up conversion
• Available in a small SOT-89-3 surface-mount package

Applications

• Battery-powered portable electronic devices requiring voltage boosting
• Low-power consumer electronics utilizing single-cell battery sources
• Embedded systems needing regulated 3.3 V supply from lower input voltages

Procurement Notes

Verify the specific suffix K6ST2G against official ABLIC documentation to confirm pinout and electrical characteristics. Ensure compatibility with existing PCB footprints for the SOT-89-3 package. Confirm that the 100 kHz switching frequency aligns with system noise requirements. Validate input voltage ranges against actual circuit conditions to prevent operation outside specified limits.

Selection Notes

Select this component when a fixed 3.3 V output is required from inputs ranging between 900 mV and 10 V. Consider the 231 mA output current capability relative to load demands. Evaluate the 23.2 uA quiescent current impact on standby power budgets. Compare the SOT-89-3 package constraints against available board space and thermal dissipation needs.

Part Context

This part belongs to the S-8352 series of switching regulators from ABLIC. It is categorized under Power Management ICs (PMIC) specifically as a DC-DC Switching Controller. The series focuses on efficient power conversion solutions for portable applications, distinguishing itself through low quiescent current operation and compact packaging options like the SOT-89-3.

Replacement Considerations

Cross-reference with other S-8352 variants or similar boost controllers from ABLIC if pinouts differ. Verify functional equivalence regarding PFM control and 100 kHz frequency before substituting. Check datasheets for alternative packages if SOT-89-3 is unavailable.
