SC804IML.TRT

Overview

The SC804IML.TRT is a synchronous step-down DC-DC converter manufactured by Semtech Corporation. It operates with an input voltage range of 2.7V to 5.5V and provides a fixed output voltage of 1.8V. The device delivers up to 3A of continuous output current. It features a switching frequency of 2.2MHz, enabling the use of small external components. The IC includes integrated power switches and is housed in a compact MLPQ-16 package.

Feature Summary

• Integrated high-side and low-side power MOSFETs for efficient synchronous rectification
• Fixed internal switching frequency reduces external component count and board space
• Built-in soft-start limits inrush current during startup
• Thermal shutdown and over-current protection ensure operational reliability

Applications

• Portable electronics requiring efficient power management
• Embedded systems with single-supply requirements
• Battery-powered devices needing stable voltage regulation

Procurement Notes

Verify the exact suffix and tape-and-reel specifications against the official Semtech datasheet before ordering. Confirm that the MLPQ-16 package dimensions match your PCB footprint design. Ensure compatibility with your target input voltage range and load requirements. Check for any recent lifecycle status updates or alternative part recommendations from the manufacturer.

Selection Notes

Select this component when a compact, high-efficiency solution is needed for converting 3.7V lithium-ion battery voltages to lower logic levels. The fixed 1.8V output suits digital cores and memory interfaces. Consider the thermal performance under maximum load conditions due to the dense packaging. Verify that the 2.2MHz frequency does not interfere with sensitive RF circuits in the system.

Part Context

This part belongs to Semtech's family of synchronous buck converters designed for space-constrained applications. It integrates control logic and power stages into a single chip. The MLPQ-16 package offers a balance between thermal dissipation and board area efficiency compared to larger packages.

Replacement Considerations

Consult Semtech documentation for direct pin-to-pin replacements or functional equivalents within the same product family. Verify that any substitute maintains the 3A current capability and 1.8V fixed output specification.
