Procurement Notes

Verify the specific suffix K2KT2U against official ABLIC documentation to confirm packaging and tape specifications. Ensure compatibility with existing PCB footprint designs for the SOT-23-5 package. Cross-reference electrical parameters with system requirements before integration. Confirm RoHS compliance status through manufacturer datasheets. Validate supply chain authenticity via authorized distributors.

Selection Notes

Select this controller when a fixed 2.5V output is required from variable low-voltage sources up to 10V. Consider the 600kHz switching frequency for balancing efficiency and component size. Evaluate the 200mA current limit against load demands. The SOT-23-5 package suits space-constrained applications. Compare with other series variants if different output voltages or frequencies are needed.

Part Context

This component belongs to the S-8351/8352 Series of CMOS step-up switching regulator controllers. These devices are designed for efficient voltage conversion in portable applications. The series emphasizes low component count and high reliability. The S-8352 variant specifically offers a fixed 2.5V output, distinguishing it from adjustable or other fixed-voltage models within the same family.

Replacement Considerations

Direct substitutes include other S-8352 series variants with identical pinouts and electrical characteristics. Verify that alternative parts match the 2.5V output and 200mA current rating. Check package compatibility for SOT-23-5. Ensure switching frequency and duty cycle specifications align with existing design constraints.
