S-8352B30MA-K4PT2G

Overview

The S-8352B30MA-K4PT2G is a synchronous rectification step-up switching regulator manufactured by ABLIC Inc. It operates within an input voltage range of 0.9 V to 10 V and provides a fixed output voltage of 3.0 V. The device supports a maximum output current of 600 mA and features a low quiescent current of 2.4 µA. It utilizes Pulse Frequency Modulation (PFM) control with a typical switching frequency of 100 kHz. The component is housed in a compact SOT-23-5 package and functions reliably across an operating temperature range of -40 °C to +85 °C.

Feature Summary

• Synchronous rectification topology for enhanced conversion efficiency
• Integrated PFM controller for optimized light-load performance
• Compact surface-mount packaging suitable for space-constrained designs

Applications

• Portable electronic devices requiring efficient power management
• Battery-powered systems utilizing single-cell lithium-ion or lithium polymer sources
• Embedded applications needing stable voltage regulation from varying input levels

Procurement Notes

Verify the specific suffix K4PT2G against official ABLIC documentation to confirm pinout compatibility and marking codes. Ensure that the required output current does not exceed the thermal limits defined in the datasheet for the SOT-23-5 package. Confirm RoHS compliance status through the manufacturer's latest environmental declarations before finalizing procurement orders.

Selection Notes

Select this component when high efficiency at moderate load currents is prioritized over ultra-low quiescent current. The synchronous design offers superior performance compared to non-synchronous alternatives in similar voltage ranges. Consider the 100 kHz switching frequency for balancing electromagnetic interference and external component size requirements.

Part Context

This part belongs to the S-8352 series of synchronous step-up regulators from ABLIC. The series is designed to provide reliable power conversion for portable electronics. The specific model indicates a 3.0 V fixed output configuration, distinguishing it from other variants in the family that offer different voltage levels or current capabilities.

Replacement Considerations

Direct replacements include other ABLIC S-8352 series variants with matching output voltages. Cross-manufacturer equivalents should be evaluated based on synchronous topology, input voltage range, and package dimensions to ensure functional parity.
