LTC3415EUHF

Voltage Regulators - DC DC Switching Regulators Overview

The LTC3415EUHF is a monolithic synchronous step-down DC-to-DC converter designed for high-efficiency power management. It features an integrated pair of complementary power MOSFETs driven by a constant frequency, current mode architecture with an internal oscillator set to a 1.5MHz switching frequency. The device supports an input voltage range from 2.5V to 5.5V and provides an adjustable output voltage between 0.6V and 5V. It delivers up to 7A of continuous output current. In typical configurations, such as stepping down 3.3V to 1.8V, it achieves efficiencies up to 92%.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm pinout and thermal characteristics. Ensure the component matches the QFN-38 package dimensions specified in the datasheet. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Confirm RoHS compliance status through the latest product specification sheet before integration into production designs.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component for applications requiring a compact, single-chip solution for currents up to 7A. The fixed 1.5MHz frequency allows for smaller external passive components compared to lower-frequency alternatives. Consider multi-phase configurations using multiple units if higher current capacity or reduced ripple is required. Ensure the input voltage range aligns with the system's power supply rails, specifically noting the 2.5V minimum limit.
