SIC401BCD-T1-GE3

Overview

The SIC401BCD-T1-GE3 is a dual-output power management integrated circuit from Vishay Siliconix, combining one synchronous step-down DC-DC converter and one low-dropout (LDO) regulator. Designed for input voltages up to 17V, it provides two regulated outputs within the MLP55-32 package. This component integrates high-efficiency switching regulation with precise linear regulation to support complex power distribution requirements in space-constrained electronic designs.

Feature Summary

• Integrates a synchronous buck converter and an LDO regulator in a single compact package
• Supports wide input voltage range up to 17V for versatile supply compatibility
• Provides two independent regulated output channels for simultaneous power delivery

Applications

• Portable electronics requiring combined switching and linear regulation
• Embedded systems with mixed analog and digital power needs
• Industrial control modules utilizing compact power solutions

Procurement Notes

Verify the specific datasheet version and ordering suffixes before procurement, as manufacturing updates may occur. Confirm that the MLP55-32 package dimensions align with your PCB footprint design. Ensure thermal management strategies are adequate for the intended operating conditions, as heat dissipation characteristics depend on board layout and ambient temperature.

Selection Notes

Select this component when a design requires both efficient switching conversion and clean linear regulation in a minimal footprint. It is suitable for applications where input voltages vary but stable, low-noise outputs are necessary for sensitive circuits. Consider the thermal performance and current capabilities relative to the specific load requirements of the target system.

Part Context

This part belongs to the SIC401 series of integrated power management devices from Vishay Siliconix. The series focuses on providing multi-function power solutions in small form factors. The SIC401BCD variant specifically combines buck and LDO technologies, distinguishing it from single-function regulators or other combinations within the broader product line.

Replacement Considerations

The SIC401BCD-T1-GE3 is functionally similar to the SIC401ACD-T1-GE3, which also integrates a buck converter and LDO regulator. Verify pin compatibility and electrical specifications before substitution, as differences in current ratings or package variants may exist between these closely related models.
