S-8357G32MC-MIRT2U

Overview

The S-8357G32MC-MIRT2U is a switching controller manufactured by ABLIC, belonging to the S-8357 series. It utilizes a Boost topology to provide a single output voltage of 3.2 V with an output current capacity of 25.9 mA. The device operates at a fixed switching frequency of 300 kHz and supports a maximum duty cycle of 78%. Designed for surface mount installation in an SOT-23-5 package, it functions within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates ultra-low standby current consumption of 25.9 µA for efficient power management
• Supports both PWM and PFM control modes for optimized efficiency across load conditions
• Features integrated synchronous rectification to minimize conduction losses

Applications

• Battery-powered portable electronic devices requiring low quiescent current
• Step-up power regulation in compact mobile hardware
• Energy-efficient consumer electronics utilizing small form factor components

Procurement Notes

Verify the specific suffix MIRT2U against official ABLIC documentation to confirm package type and tape/reel specifications. Ensure compatibility with SOT-23-5 footprint requirements during PCB layout. Confirm RoHS compliance status through the manufacturer's environmental declaration prior to integration into regulated assemblies.

Selection Notes

Select this component when a compact boost converter with minimal standby current is required. The 3.2 V fixed output suits applications needing precise voltage levels without external resistor networks. Consider the 300 kHz frequency for balancing component size and noise performance in space-constrained designs.

Part Context
