S-8352D33MC-K8ST2G

Overview

The S-8352D33MC-K8ST2G is a positive output step-up DC-DC controller IC from ABLIC Inc., housed in a SOT-23-5 package. It operates as a boost regulator with a switching frequency of 100 kHz and a maximum duty cycle of 75%. The device supports an output voltage range of 2 V to 6.5 V and provides an output current capability of 25 mA.

Feature Summary

• Positive output step-up DC-DC control topology
• Integrated 100 kHz switching frequency operation
• Maximum 75% duty cycle capability

Applications

• Battery-powered portable electronics requiring voltage boosting
• Low-power embedded systems needing stable higher voltage rails
• General-purpose step-up regulation for small form-factor devices

Procurement Notes

Verify the exact suffix K8ST2G against official ABLIC documentation to confirm pinout and electrical specifications. Ensure compatibility with external components such as inductors and diodes, as this is a controller IC requiring peripheral parts. Confirm RoHS compliance status through the manufacturer's latest datasheet before integration into production designs.

Selection Notes

Select this component when a compact SOT-23-5 footprint is required for boost applications. It is suitable for designs needing a fixed 100 kHz switching frequency and moderate output current up to 25 mA. Consider external component selection carefully, as the IC controls rather than directly supplies power. Verify input voltage ranges match the specific application requirements.

Part Context

This part belongs to the ABLIC S-8352 series of switching controllers. It is designed for efficient power management in space-constrained environments. The SOT-23-5 package allows for surface-mount assembly, facilitating automated manufacturing processes. It serves as a core control element in step-up converter circuits.

Replacement Considerations

Check for direct pin-to-pin replacements within the S-8352 family or other ABLIC boost controllers. Ensure any substitute matches the 100 kHz frequency and 25 mA output current limits. Verify that alternative packages are compatible with existing PCB footprints.
