SIC414CD-T1-GE3

Overview

The SIC414CD-T1-GE3 is a dual-output power management IC from Vishay Siliconix, featuring a synchronous step-down (buck) converter and a linear regulator. It operates with an input voltage range of 3 V to 28 V. The buck converter provides an adjustable output voltage between 750 mV and 5.5 V with a maximum output current of 6 A. The switching frequency ranges from 200 kHz to 1 MHz. The device includes a linear regulator for additional supply needs. It is housed in an MLPQ55-32 package and supports surface mount installation.

Feature Summary

• Integrates a synchronous buck converter and a linear regulator into a single compact package
• Supports wide input voltage range suitable for various bus voltages
• Features adjustable output voltage for the DC/DC converter section

Applications

• Microprocessor voltage regulation
• High-current current-limited switch applications
• DVD player power systems

Procurement Notes

Verify the specific suffix and tape/reel configuration against the manufacturer's latest datasheet before ordering. Confirm that the MLPQ55-32 footprint matches your PCB design constraints. Ensure thermal management solutions are adequate for the expected load conditions, as power dissipation varies with input-output differential and current draw.

Selection Notes

Select this component when a combined solution for high-current digital logic and auxiliary analog supplies is required. The integrated topology reduces board space compared to discrete implementations. Consider the operating temperature range and thermal resistance of the MLPQ55-32 package relative to your enclosure design. Verify compatibility with the target microprocessor's power-up and power-down sequencing requirements.

Part Context

This part belongs to the MicroBUCK family of power management ICs designed by Vishay Siliconix. These devices are engineered to simplify power distribution networks in portable and industrial electronics. The integration of switching and linear regulation addresses the need for clean, stable power rails in complex system-on-chip environments.

Replacement Considerations

Check for direct pin-to-pin replacements within the same MicroBUCK series or newer generations from Vishay. Evaluate alternative PMICs from other manufacturers if lead times are critical, ensuring equivalent output current and voltage specifications are met.
