LT3663EDCB

Overview

The LT3663EDCB-5 is an automotive-grade, current-mode step-down switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 7.5V to 36V and provides a fixed output voltage of 5V at up to 1.2A. The device features a programmable output current limit that accurately controls system power dissipation. It utilizes a buck topology and is available in an 8-pin DFN EP package.

Feature Summary

Current mode control architecture for stable regulation
Programmable output current limit for precise power management
Automotive qualification for reliable operation in vehicle environments

Applications

Automotive electronic systems requiring regulated power
Industrial DC/DC step-down conversion applications
Embedded systems needing isolated or non-isolated power regulation

Procurement Notes

Verify the specific suffix (e.g., -5 for 5V output) when ordering, as the base model number covers multiple voltage variants. Confirm automotive grade requirements against the datasheet specifications. Check availability status through authorized distributors, as supply levels may vary. Ensure the 8-pin DFN EP package fits the target PCB layout constraints before finalizing procurement.

Selection Notes

Select this component for applications requiring a robust buck converter with integrated current limiting. The fixed 5V output variant suits systems needing standard logic or peripheral voltages. Consider the 7.5V to 36V input range compatibility with vehicle battery systems. Evaluate thermal performance within the DFN EP package for the expected load conditions.

Part Context

The LT3663 series comprises synchronous buck regulators designed for high efficiency and compact size. The EDCB suffix indicates the automotive grade version with enhanced reliability standards. This part belongs to a family of converters offering various output voltages and packages to suit diverse power management needs in industrial and automotive sectors.

Replacement Considerations

LT3663EDCB-3.3: Provides a 3.3V fixed output instead of 5V. LT3663IDCB-5: Industrial grade version with similar electrical characteristics but different temperature rating.
