LTC3676HLXE-1#PBF

Special Purpose Regulators Overview

The LTC3676HLXE-1#PBF is a seven-output synchronous buck switching regulator designed for application processor power management. It operates with an input voltage range of 2.7 V to 5.5 V and provides adjustable output voltages from 800 mV to 5.5 V. The device delivers up to 2.5 A per channel and supports switching frequencies between 1.125 MHz and 2.25 MHz. It features a low operating supply current of 23 uA and functions within a temperature range of -40°C to +150°C in an LQFP-48 package.

Special Purpose Regulators Feature Summary

• Integrates seven independent synchronous buck converters for multi-rail power distribution
• Supports high-frequency operation to minimize external component size
• Includes shutdown capability for power management efficiency
• Designed specifically for complex application processor power architectures

Special Purpose Regulators Applications

• Application processor power supply systems
• Multi-voltage rail generation for system-on-chip platforms
• Portable computing devices requiring multiple regulated outputs
• Industrial control systems with complex logic requirements

Special Purpose Regulators Procurement Notes

Verify the specific suffix and tape-and-reel or tray packaging details directly with Analog Devices or authorized distributors, as availability may vary. Confirm RoHS compliance status and moisture sensitivity level prior to ordering. Ensure the LQFP-48 footprint matches your PCB design constraints. Check for any recent product change notices that might affect pinout or electrical characteristics.

Special Purpose Regulators Selection Notes

Select this component when a single IC solution is required to generate multiple low-voltage rails from a standard 3.3 V or 5 V source. It is suitable for designs needing synchronized switching to reduce EMI or independent frequency adjustment for noise optimization. Consider thermal performance in the LQFP-48 package if high total output current is expected across all seven channels simultaneously.

Special Purpose Regulators Part Context

This part belongs to the LTC3676 family of multi-output DC/DC controllers. It is distinct from single-output regulators like the LTC3615 or high-voltage controllers like the LTC7810. The device integrates power switches and control circuitry into one package, simplifying board layout compared to discrete solutions using separate controllers and MOSFETs for each rail.

Special Purpose Regulators Replacement Considerations

No direct public substitute part numbers are confirmed in the provided documentation. Evaluate other members of the LTC36xx series for similar multi-output configurations, ensuring compatibility with input voltage ranges and output current requirements.
