S-8358B35MC-NQUT2G

Overview

The S-8358B35MC-NQUT2G is a step-up switching controller from the ABLIC S-8358 series, designed for DC-DC conversion applications. It operates within an input voltage range of 0.9V to 10V and provides a fixed output voltage of 3.5V. The device features a low quiescent current of 25.9µA and supports a switching frequency of 100kHz with a maximum duty cycle of 90%. It utilizes PWM/PFM control modes and is housed in a compact SOT-23-5 package. The component is rated for operation between -40°C and +85°C.

Feature Summary

Integrates PWM/PFM hybrid control for optimized efficiency across varying load conditions
Features ultra-low quiescent current consumption to extend battery life in portable devices
Supports wide input voltage range suitable for single-cell lithium-ion battery applications

Applications

Portable electronic devices requiring efficient power management
Battery-powered equipment utilizing single-cell lithium-ion power sources
General-purpose DC-DC step-up conversion circuits

Procurement Notes

Verify the specific suffix NQUT2G against official ABLIC documentation to confirm pinout compatibility and marking codes. Ensure that the ordering information matches the exact part number required for your design, as suffix variations may indicate differences in packaging or tape-and-reel specifications. Cross-reference with the latest datasheet revision history to account for any recent manufacturing changes.

Selection Notes

Select this component when a fixed 3.5V output is required from a variable input source within the 0.9V to 10V range. Consider the 25.9µA quiescent current for standby power constraints. Verify that the SOT-23-5 package fits the PCB layout constraints and that the 100kHz switching frequency aligns with external inductor selection requirements for the target application.

Part Context

This part belongs to the S-8358 series of step-up switching controllers manufactured by ABLIC Inc. The series is characterized by low power consumption and compact packaging options like SOT-23-5. These controllers are designed to drive external MOSFETs for efficient voltage boosting in space-constrained designs.
