SC414MLTRT

Overview

The SC414MLTRT is a dual-output power management IC from Semtech’s SmartDrive series, housed in a 28-MLPQ (4x4 mm) surface-mount package. It integrates one synchronous buck converter and one low-dropout linear regulator. The buck output delivers up to 6A with an adjustable voltage range of 750 mV to 5.5 V, while the LDO provides a fixed 5V at 150 mA. Operating from a 3 V to 28 V input supply, it features a 1 MHz switching frequency and functions within a -40°C to +85°C temperature range.

Feature Summary

• Integrates a high-current synchronous buck converter and a dedicated LDO in a single compact package
• Supports wide input voltage ranges suitable for various bus architectures
• Utilizes internal power FETs to minimize external component count and board space

Applications

• Portable electronic devices requiring multiple regulated voltage rails
• Industrial control systems needing robust power regulation
• Embedded computing platforms with mixed analog and digital load requirements

Procurement Notes

Verify current availability status as the component may be obsolete or subject to last-time buy restrictions. Confirm that the 28-MLPQ footprint matches your PCB layout constraints. Ensure thermal design accounts for the exposed pad requirement to maintain reliability under specified operating temperatures.

Selection Notes

Select this device when space-constrained designs require both high-current switching regulation and clean linear power for sensitive loads. Evaluate thermal performance based on the specific duty cycle and ambient conditions. Consider the 1 MHz frequency for balancing efficiency against passive component size.

Part Context

Part of the SC414 family within Semtech’s SmartDrive portfolio, designed for efficient power conversion in portable and industrial applications. The MLPQ package offers a small footprint relative to its power handling capabilities, supporting modern miniaturization trends in electronics manufacturing.

Replacement Considerations

Check for direct cross-references from Semtech or authorized distributors. Verify pin compatibility and electrical specifications if considering alternative PMICs from other manufacturers.
