S-8352D20MC-K8FT2G

Overview

The S-8352D20MC-K8FT2G is a DC-DC switching controller IC manufactured by ABLIC Inc. It utilizes a boost topology to provide a fixed output voltage of 2 V. The device operates with an input supply voltage range from 0.9 V to 10 V and features a switching frequency of 100 kHz. It is housed in a compact SOT-23-5 package suitable for surface mount installation. The component supports a maximum duty cycle of 75% and functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Integrates a boost switching controller for step-up DC-DC conversion applications
• Supports external power switches via synchronous rectifier control without internal MOSFETs
• Operates over a wide input voltage range starting from 0.9 V

Applications

• Battery-powered portable electronic devices requiring voltage boosting
• Low-voltage systems needing regulated higher output voltages
• General-purpose DC-DC converter designs using external power components

Procurement Notes

Verify the specific suffix K8FT2G against official ABLIC documentation to confirm pinout and electrical characteristics. Ensure compatibility with external power stages, as this is a controller rather than a complete regulator. Confirm RoHS compliance status through current datasheets before finalizing procurement specifications.

Selection Notes

Select this component when a fixed 2 V output is required from variable or low input sources. It is appropriate for designs where external power switches are preferred for thermal management or current handling. Consider the 100 kHz switching frequency for filter component sizing and efficiency requirements in space-constrained PCB layouts.

Part Context

This part belongs to the ABLIC S-8352 series of DC-DC switching controllers. Unlike integrated regulators, these controllers manage external power elements to achieve efficient voltage conversion. The series is designed for low-power applications requiring precise voltage regulation in small form factors.

Replacement Considerations

Direct replacements must match the SOT-23-5 package, 2 V fixed output, and 100 kHz switching frequency. Verify that alternative controllers support the same 0.9 V to 10 V input range and 75% duty cycle limit. Cross-reference pinouts carefully as controller interfaces vary significantly between manufacturers.
