S-8355M60MC-MDTT2U

Overview

The S-8355M60MC-MDTT2U is a boost switching controller manufactured by ABLIC Inc. It operates within an input voltage range of 0.9V to 10V and delivers a fixed output voltage of 6.0V. The device features a switching frequency of 600kHz with a maximum duty cycle of 85%. It supports surface mount installation in an SOT-23-5 package and functions reliably across a temperature range of -40°C to +85°C.

Feature Summary

• Implements synchronous rectification for improved power conversion efficiency
• Integrates clock synchronization capability for noise reduction in multi-unit systems
• Includes an enable pin for precise power management control

Applications

• Battery-powered portable electronic devices requiring efficient step-up regulation
• Industrial sensor modules operating from low-voltage sources
• Embedded systems utilizing single-cell lithium-ion or alkaline batteries

Procurement Notes

Verify the specific suffix codes against official datasheets to ensure correct output voltage, package type, and tape/reel specifications. Confirm RoHS compliance status and manufacturing origin prior to ordering. Cross-reference part numbers with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when a fixed 6.0V output is required from variable low-voltage inputs. The 600kHz frequency allows for smaller external passive components compared to lower-frequency alternatives. Ensure the application requires synchronous rectification and clock synchronization features not available in standard non-synchronous variants.

Part Context

This part belongs to the ABLIC S-8355 series, designed as high-efficiency boost controllers. Unlike the S-8356 or S-8357 series which may lack certain advanced features, the S-8355 integrates synchronous rectification and clock sync capabilities directly into the controller architecture for optimized performance in compact designs.

Replacement Considerations

Direct replacements include other S-8355 series variants with different output voltages, such as S-8355M33MC-MDTT2U (3.3V) or S-8355M50MC-MDTT2U (5.0V), provided the system voltage requirements are adjusted accordingly.
