S-8352A37MC-K2WT2G

Overview

The S-8352A37MC-K2WT2G is a positive output step-up DC-DC controller IC manufactured by ABLIC Inc. It operates with PFM control at a switching frequency of approximately 100 kHz and features a very low quiescent current of 23.2 uA. The device supports an input voltage range from 900 mV to 10 V and provides a fixed output voltage of 3.7 V. It is housed in a compact SOT-23-5 package, suitable for surface mount installation.

Feature Summary

• Integrates PFM control for efficient step-up regulation
• Features ultra-low quiescent current consumption
• Supports wide input voltage ranges for flexible power designs

Applications

• Portable electronic devices requiring efficient power management
• Battery-powered systems needing step-up voltage conversion
• Compact consumer electronics with space constraints

Procurement Notes

Verify the specific suffix K2WT2G against official ABLIC documentation to confirm package type and tape/reel specifications. Ensure compatibility with your PCB footprint for the SOT-23-5 package. Cross-reference the part number with authorized distributors to avoid counterfeit components. Confirm that the fixed 3.7 V output meets your system requirements before procurement.

Selection Notes

Select this component when a fixed 3.7 V output is required from a variable or lower input source. The low quiescent current makes it suitable for battery-operated applications where standby power consumption is critical. The SOT-23-5 package offers a small form factor for space-constrained designs. Verify that the 100 kHz switching frequency aligns with your EMI and filter design constraints.

Part Context

This part belongs to the S-8352 series of switching controllers from ABLIC Inc., designed for high-efficiency power management in portable devices. The series focuses on minimizing power loss through advanced control techniques and low standby currents.

Replacement Considerations

Check for direct pin-to-pin replacements within the S-8352 family with different output voltages if 3.7 V is not suitable. Verify electrical parameters such as quiescent current and switching frequency against alternative models from other manufacturers.
