S-8352A32MC-K2RT2G

Overview

The S-8352A32MC-K2RT2G is a step-up switching regulator controller manufactured by ABLIC Inc. It operates with a fixed output voltage of 3.2 V and supports an input supply range from 0.9 V to 10 V. The device utilizes PFM modulation at a switching frequency of 100 kHz, achieving a typical quiescent current of 23.2 uA. It is housed in a compact SOT-23-5 package (SC-74A) and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates PFM control for optimized efficiency during light-load conditions
• Features low quiescent current consumption to extend battery life
• Supports wide input voltage range for flexible power source compatibility

Applications

• Battery-powered portable electronic devices
• Low-power sensor nodes requiring efficient voltage boosting
• Mobile communication equipment with strict power constraints

Procurement Notes

Verify the specific suffix K2RT2G against official ABLIC documentation to confirm package type and reel specifications. Ensure the ordering code matches the required SOT-23-5 configuration. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and production status before procurement.

Selection Notes

Select this component when a fixed 3.2 V output is required from a low-voltage source. The 100 kHz switching frequency balances component size and efficiency. Consider the 23.2 uA quiescent current for applications prioritizing standby power conservation over high-current delivery capabilities.

Part Context

This part belongs to the S-8352 series of step-up switching regulators. It shares architectural similarities with other models in the family but is distinguished by its specific output voltage setting and packaging variant. The series targets applications needing reliable voltage regulation in space-constrained environments.

Replacement Considerations

Direct substitutes include S-8352A32MC-K2RT2U and S-8352C32UA-K6RT2G, provided pinout and electrical characteristics align with system requirements. Verify package compatibility and thermal performance when transitioning between variants.
