SC417MLTRT

Overview

The SC417MLTRT is a dual-output power management IC from the Semtech EcoSpeed series, featuring a synchronous buck regulator and a linear LDO. It operates within an input voltage range of 3 V to 28 V. The primary switching output delivers up to 10 A with an adjustable voltage range of 0.5 V to 5.5 V. The secondary LDO provides a fixed 5 V output at 200 mA. Operating at a 1 MHz switching frequency, it utilizes a 32-MLPQ (5x5) surface-mount package. The device supports operation between -40°C and +85°C.

Feature Summary

• Integrates a high-current synchronous buck converter with a dedicated low-dropout regulator in a single compact package.
• Supports wide input voltage ranges suitable for various industrial and automotive bus architectures.
• Features programmable switching frequency for optimized efficiency and noise performance.
• Includes integrated protection mechanisms for thermal and current limiting.

Applications

• Industrial automation control systems
• Automotive infotainment and gateway modules
• Telecommunications base station equipment
• Point-of-load regulation for FPGA or ASIC cores

Procurement Notes

Verify component authenticity through authorized distributors due to obsolete status. Confirm RoHS compliance and lead-free soldering specifications. Check for specific tape-and-reel packaging requirements compatible with automated assembly lines. Ensure storage conditions meet moisture sensitivity level standards prior to reflow soldering.

Selection Notes

Select this component when a combined high-current switching solution and auxiliary LDO are required in a space-constrained design. Consider the 32-pin MLPQ footprint for PCB layout constraints. Evaluate thermal dissipation capabilities given the 10 A output capability. Compare against single-output alternatives if the LDO function is unnecessary to reduce cost and complexity.

Part Context

Part of the SC41x family of integrated FET regulators designed for high-efficiency power conversion. Shares architectural similarities with SC417MLTRC but differs in packaging and termination style. Related evaluation boards include the SC417EVB for performance validation. The series targets applications requiring robust power management in harsh environments.

Replacement Considerations

SC417MLTRC is a related variant within the same product family. Verify pin compatibility and thermal pad configuration before substitution.
