S-8355M60MC-MDTT2G

Overview

The S-8355M60MC-MDTT2G is a step-up switching regulator controller manufactured by ABLIC Inc. It operates with a fixed 600 kHz switching frequency and utilizes PWM control. The device supports an input voltage range of 0.9 V to 10 V and provides a fixed output voltage of 6.0 V. It is housed in a super-small SOT-23-5 package, designed for surface mount installation. The component functions within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates a high-frequency 600 kHz oscillator for compact external component sizing
• Features a super-small SOT-23-5 package footprint for space-constrained designs
• Supports wide input voltage operation from 0.9 V up to 10 V

Applications

• Portable electronic devices requiring efficient power conversion
• Battery-powered systems utilizing single-cell lithium-ion sources
• Compact consumer electronics with limited PCB area

Procurement Notes

Verify the specific suffix MDTT2G against official ABLIC documentation to confirm tape-and-reel packaging specifications and marking codes. Ensure compatibility with standard SOT-23-5 footprints during layout design. Cross-reference the fixed 6.0 V output requirement with system load needs before finalizing procurement orders.

Selection Notes

Select this model when a fixed 6.0 V boost output is required alongside minimal board space constraints. The 600 kHz frequency allows for smaller inductors compared to lower-frequency alternatives. Verify that the external switch transistor meets the current requirements, as this is a controller without an integrated power FET.

Part Context

This component belongs to the S-8355 series of step-up switching regulators. The series is characterized by its small package options and high switching frequencies, targeting applications where size efficiency and power density are critical priorities for portable and embedded systems.

Replacement Considerations

Check for S-8355 variants with different output voltages or package types if the 6.0 V setting does not match the target application requirements.
