SC2544MLTRT

Overview

The SC2544MLTRT is a dual switching controller manufactured by Semtech Corporation, designed for step-down DC-DC applications. It operates with a voltage-mode control topology and supports a maximum switching frequency of 300kHz. The device provides two positive output channels, each capable of delivering up to 0.5A. It is housed in a 24-MLPQ package measuring 4x4 mm and is RoHS compliant. This component functions as a dedicated controller requiring external power switches.

Feature Summary

• Dual channel architecture supporting independent or synchronized buck regulation
• Voltage-mode control strategy for stable operation under varying load conditions
• Integrated transistor driver outputs for efficient gate drive of external MOSFETs

Applications

• Multi-rail power distribution systems
• Industrial equipment power supplies
• Telecommunications infrastructure

Procurement Notes

Verify the specific suffix and tape-and-reel quantity requirements against your manufacturing needs. Confirm that the 24-MLPQ footprint matches your PCB layout constraints. Ensure compatibility with external components selected for the 300kHz switching frequency. Check for any recent product change notices regarding pinout or electrical characteristics before finalizing the bill of materials.

Selection Notes

Select this component when a dual-output synchronous buck solution is required without integrated power stages. It is suitable for designs needing precise voltage-mode control rather than current-mode. Consider the thermal performance of the MLPQ package if high ambient temperatures are expected. Evaluate the need for external compensation networks based on the stability requirements of the chosen inductors.

Part Context

This part belongs to Semtech's portfolio of PMIC switching controllers. It complements single-channel regulators by providing dual outputs in a compact form factor. The MLPQ package allows for dense board layouts in space-constrained electronic devices. It serves as a core control element in complex power management architectures.

Replacement Considerations

Direct substitutes may include other dual buck controllers from Semtech with similar pinouts and frequencies. Verify that alternative parts support the same 0.5A per channel output capability. Ensure the replacement maintains the 24-MLPQ package dimensions for mechanical compatibility.
