S-8358B23MC-NQIT2U

Overview

The S-8358B23MC-NQIT2U is a boost switching controller from ABLIC Inc. designed for step-up DC-DC applications. It operates within an input voltage range of 0.9V to 10V and delivers a fixed output voltage of 2.3V. The device features a switching frequency of 100kHz with a maximum duty cycle of 90%. It utilizes a non-synchronous rectifier topology and provides one output phase. The component is housed in a compact SOT-23-5 package, suitable for surface mount installation.

Feature Summary

• Integrated boost switching controller for efficient step-up power conversion
• Fixed 2.3V output configuration simplifies circuit design
• Operates across a wide input voltage range from 0.9V to 10V
• Compact SOT-23-5 package facilitates space-constrained layouts

Applications

• Battery-powered portable electronic devices requiring voltage boosting
• Low-voltage systems needing stable 2.3V supply rails
• Industrial control modules operating within specified temperature ranges

Procurement Notes

Verify the exact suffix NQIT2U against official ABLIC documentation to confirm pinout and electrical specifications. Ensure compatibility with existing PCB footprints for the SOT-23-5 package. Confirm that the 100kHz switching frequency aligns with system noise requirements. Validate that the non-synchronous design meets efficiency targets for the intended load conditions.

Selection Notes

Select this component when a fixed 2.3V output is required from variable or low input sources up to 10V. The 100kHz frequency offers a balance between component size and efficiency. Consider the non-synchronous nature for cost-sensitive designs where peak efficiency is less critical than simplicity. Ensure the application environment supports the standard commercial or industrial temperature ratings associated with this series.

Part Context

This part belongs to the S-8358 series of boost controllers from ABLIC. The series is characterized by its ability to handle high input voltages while maintaining stable output regulation. The S-8358 family is commonly used in applications requiring reliable step-up conversion in compact form factors, leveraging ABLIC's expertise in power management integrated circuits.

Replacement Considerations

Direct substitutes must match the 2.3V output, 100kHz frequency, and SOT-23-5 package. Verify if alternative parts support the same 0.9V-10V input range. Check for synchronous vs. non-synchronous differences as this affects efficiency and external component selection.
