S-8358H30MC-NUPT2U

Overview

The S-8358H30MC-NUPT2U is a step-up switching regulator controller from ABLIC, designed for low-power applications. It operates with an input voltage range of 0.7 V to 6 V and provides a fixed output voltage of 3.0 V. The device features a typical quiescent current of 25.9 µA and supports PWM/PFM auto-switching modes. It is housed in a compact SOT-23-5 package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates PWM/PFM auto-switching control to optimize efficiency across varying load conditions.
• Utilizes high-withstand voltage CMOS process technology for robust operation.
• Features a compact SOT-23-5 surface-mount package for space-constrained designs.

Applications

• Battery-powered portable electronic devices
• Low-power sensor nodes
• Wearable health monitoring equipment

Procurement Notes

Verify the specific suffix NUPT2U against the official ABLIC datasheet to confirm pinout compatibility and electrical tolerances. Ensure the ordering quantity aligns with manufacturer reel specifications. Cross-reference the RoHS compliance status directly with the latest product documentation before finalizing procurement decisions.

Selection Notes

Select this component when a fixed 3.0 V output is required from a single-cell lithium battery or similar low-voltage source. The low quiescent current makes it suitable for standby-sensitive applications. Verify that the external inductor and capacitor values meet the stability requirements specified in the application circuit guidelines.

Part Context

This part belongs to the S-8358 series of step-up switching regulator controllers. The series is characterized by its ability to maintain high efficiency at light loads through automatic mode switching. It is distinct from linear regulators by its capability to boost input voltages below the desired output level.

Replacement Considerations

Direct substitutes include other S-8358 variants with different output voltages, such as S-8358J33MC-NWST2U (3.3 V) or S-8358H23MC-NUIT2G (2.3 V), provided the system design accommodates the voltage difference. Ensure pin compatibility remains unchanged.
