S-8358J33MC-NWST2G

Overview

The S-8358J33MC-NWST2G is a step-up switching regulator controller from ABLIC, designed for battery-powered applications. It features a fixed 3.3 V output voltage and operates within an input voltage range of 0.9 V to 10 V. The device integrates PWM/PFM control modes to optimize efficiency across load conditions, achieving a typical quiescent current of 25.9 uA. It supports a maximum switching frequency of 600 kHz and delivers up to 231 mA output current. The component functions reliably between -40°C and +85°C, housed in a compact SOT-23-5 package suitable for surface-mount assembly.

Feature Summary

Integrates PWM/PFM hybrid control architecture to maintain high conversion efficiency under varying load conditions.
Features ultra-low standby current consumption to extend operational time in portable devices.
Includes built-in protection mechanisms against over-current and thermal overload events.

Applications

Mobile communication devices
Portable electronic equipment
Battery-operated instruments

Procurement Notes

Verify the specific suffix 'NWST2G' against official ABLIC documentation to confirm tape-and-reel packaging specifications and marking codes. Ensure compatibility with standard SMD reflow processes. Cross-reference the RoHS compliance status directly with the manufacturer's latest environmental declaration prior to final procurement approval.

Selection Notes

Select this model when a fixed 3.3 V boost output is required with minimal quiescent current draw. The integrated PWM/PFM mode offers superior light-load efficiency compared to single-mode controllers. Consider the 600 kHz switching frequency for smaller external passive component sizing while maintaining stable regulation within the specified temperature range.

Part Context

This component belongs to the S-8358 series of step-up switching regulators. The series is characterized by low power consumption and high integration levels, targeting extended battery life in consumer electronics. The J33 variant specifically denotes the fixed 3.3 V output configuration within this product family.
