S-8356Q31MC-OYQT2G

Overview

The S-8356Q31MC-OYQT2G is a step-up switching regulator controller manufactured by ABLIC Inc. It operates within an input voltage range of 0.9 V to 10 V and delivers a fixed output voltage of 3.1 V. The device features a low quiescent current of 25.9 uA and supports a maximum duty cycle of 85%. It utilizes PWM/PFM control modes with a switching frequency of 600 kHz. Designed for surface-mount installation, it is housed in a compact SOT-23-5 package and functions reliably across a temperature range of -40°C to +85°C.

Feature Summary

• Integrates PWM/PFM hybrid control architecture for optimized efficiency across varying load conditions
• Features ultra-low standby current consumption suitable for battery-powered portable applications
• Supports wide input voltage ranges up to 10 V for flexible power supply configurations

Applications

• Portable electronic devices requiring extended battery life
• Battery-powered sensor modules
• Low-power consumer electronics

Procurement Notes

Verify the specific suffix OYQT2G against official ABLIC documentation to confirm tape-and-reel packaging quantities and RoHS compliance status. Ensure the ordering quantity aligns with manufacturer minimums. Cross-reference the datasheet revision date to validate technical specifications prior to integration.

Selection Notes

Select this component when a fixed 3.1 V boost output is required from a single-cell lithium battery or similar low-voltage source. The SOT-23-5 footprint minimizes board space usage. Verify that the 600 kHz switching frequency does not interfere with sensitive RF circuits in the design environment.

Part Context

This part belongs to the S-8356 series of step-up switching regulators from ABLIC. The series is characterized by high efficiency and low current consumption. The Q31 variant specifically provides a 3.1 V output, distinguishing it from other models offering different fixed voltage levels within the same family.

Replacement Considerations

Compatible substitutes include S-8356M31MC-MEPT2U and S-8356K31MC-NEVT2U. These parts share identical electrical characteristics and pinouts but differ in packaging suffixes. Confirm availability and lead times before substitution.
