S-8358B60UA-NRTT2G

Overview

The S-8358B60UA-NRTT2G is a step-up switching regulator controller manufactured by ABLIC Inc. It operates within an input voltage range of 900 mV to 10 V and provides a fixed output voltage of 6.0 V. The device utilizes PWM control topology and features a low quiescent current of 18.7 uA. It supports a maximum output current of 231 mA and functions at a switching frequency of 50 kHz. The component is rated for operation between -40°C and +85°C, housed in an SOT-89-3 package.

Feature Summary

• Integrates PWM control for efficient step-up voltage conversion
• Maintains low power consumption with minimal quiescent current draw
• Supports wide input voltage ranges for flexible power supply designs

Applications

• Battery-powered portable electronic devices requiring voltage boosting
• General-purpose DC-DC conversion in consumer electronics
• Power management systems in industrial instrumentation

Procurement Notes

Verify the specific suffix NRTT2G against official ABLIC documentation to confirm packaging and tape-and-reel specifications. Ensure compatibility with existing PCB footprints for the SOT-89-3 package. Cross-reference thermal requirements with system design constraints. Confirm RoHS compliance status through manufacturer datasheets prior to integration.

Selection Notes

Select this component when a fixed 6.0 V output is required from variable or lower input sources. The 50 kHz switching frequency allows for smaller external passive components compared to lower-frequency alternatives. Consider the 231 mA output limit for load requirements. The SOT-89-3 package offers a compact solution for space-constrained applications.

Part Context

This part belongs to the S-8358 series of switching regulators from ABLIC. The series includes various output voltage options and package types. The S-8358 family is designed for high-efficiency power management in portable devices. It shares common control architecture with other models in the lineup but differs in fixed output settings and physical packaging.

Replacement Considerations

Direct substitutes include other S-8358 series variants with different fixed output voltages if system requirements change. Verify pinout compatibility before replacing with similar boost controllers from other manufacturers. Check thermal performance and efficiency curves against original design specifications.
