S-8358B26MC-NQLT2G

Overview

The S-8358B26MC-NQLT2G is a step-up switching regulator controller from the ABLIC S-8358 series, designed for efficient DC-DC conversion. It features an integrated oscillator and operates with a fixed switching frequency of 600 kHz to minimize external component size. The device supports input voltages ranging from 0.9 V to 10 V and provides a precise output voltage of 2.6 V. With a typical quiescent current of 25.9 µA, it ensures low power consumption in standby modes. Operating within a temperature range of -40°C to +85°C, it is housed in a compact SOT-23-5 package suitable for space-constrained portable applications.

Procurement Notes

Verify the specific suffix NQLT2G against official ABLIC documentation to confirm tape-and-reel packaging and marking codes. Ensure compatibility with your PCB footprint for the SOT-23-5 package. Cross-reference the 2.6 V output specification with your system requirements. Confirm RoHS compliance status through the manufacturer's latest environmental declaration before final procurement approval.

Selection Notes

Select this component when a fixed 2.6 V output is required from an input range of 0.9 V to 10 V. The S-8358 series is appropriate for designs prioritizing low quiescent current and minimal external component count. Consider the SOT-23-5 package constraints for thermal management. Verify that the 600 kHz switching frequency aligns with EMI constraints in your specific application environment.
