S-8355M34MC-MCTT2U

Overview

The ABLIC S-8355M34MC-MCTT2U is a step-up switching regulator controller designed for portable applications. It operates with an input voltage range of 0.9V to 3.1V and provides a fixed output voltage of 3.4V. The device features a low quiescent current of 25.9µA and supports a maximum output current of 282mA. It utilizes PWM control at a switching frequency of 250kHz and is housed in a compact SOT-23-5 package, suitable for surface mount installation.

Feature Summary

Integrates high-withstand voltage CMOS process technology for reliable operation
Supports both PWM and PFM modes for optimized efficiency across load ranges
Includes built-in protection functions against overcurrent and thermal issues

Applications

Battery-powered portable electronic devices
Low-voltage power supply systems
Mobile communication equipment

Procurement Notes

Verify the complete part number including suffixes to ensure correct output voltage and package configuration. Confirm RoHS compliance status through official documentation before procurement. Check manufacturing lead times as production cycles may vary. Ensure compatibility with existing PCB footprint designs for the specified SOT-23-5 package.

Selection Notes

Select this component when a fixed 3.4V output is required from a single-cell lithium battery source. Consider the 250kHz switching frequency for balancing component size and efficiency. Evaluate the 282mA output current capability against peak load requirements. Verify that the 0.9V minimum input voltage aligns with the discharge curve of the intended power source.

Part Context

This device belongs to the S-8355 series of step-up switching regulators from ABLIC. The series is characterized by its use of high-withstand voltage CMOS processes, enabling robust performance in low-voltage environments. The S-8355 models are specifically engineered for applications requiring efficient power conversion from single-cell batteries.
