S-8352C31UA-K6QT2G

Overview

The S-8352C31UA-K6QT2G is a positive output, step-up DC-DC controller IC manufactured by ABLIC Inc. It utilizes a boost topology to regulate voltage levels in surface-mount applications. The component operates with a fixed switching frequency of 100kHz and features a low quiescent current of 23.2µA. It is housed in a compact SOT-89-3 package and supports an input voltage range starting from 0.9V. The device is designed for efficient power management in portable electronics.

Feature Summary

• Integrates a PFM control scheme for optimized efficiency at light loads
• Features a compact SOT-89-3 surface mount package for space-constrained designs
• Provides stable step-up regulation with low standby current consumption

Applications

• Portable battery-powered devices requiring voltage boosting
• Mobile communication equipment power stages
• Consumer electronics with limited power budgets

Procurement Notes

Verify the specific suffix K6QT2G against the official ABLIC datasheet to confirm pinout and electrical tolerances. Ensure compatibility with the target PCB footprint for the SOT-89-3 package. Confirm that the 100kHz switching frequency aligns with external inductor selection requirements. Check for any recent PCN updates regarding material composition or marking changes before finalizing procurement orders.

Selection Notes

Select this component when a fixed 3.1V output boost controller is required with minimal quiescent current. The SOT-89-3 package offers a balance between thermal performance and board space. Consider the 100kHz switching frequency for inductor size trade-offs. Ensure the input voltage source can support the minimum operating voltage of 0.9V for reliable startup under all load conditions.

Part Context

This part belongs to the S-8352 series of step-up controllers from ABLIC. The series is characterized by low power consumption and high integration. The S-8352C31 variant specifically targets applications needing a fixed output voltage. It complements other PMIC solutions by providing a simple, cost-effective boost regulation stage for single-cell battery systems.

Replacement Considerations

Direct substitutes include the S-8352C32UA-K6RT2G for a 3.2V output option within the same package family. Verify functional equivalence with other ABLIC S-8352 variants if different output voltages are acceptable. Cross-reference pinouts carefully as suffixes may indicate minor packaging or marking differences.
