LT3506AIFE#PBF

Overview

The LT3506AIFE#PBF is a dual monolithic synchronous step-down DC/DC converter manufactured by Analog Devices Inc. It integrates two independent buck regulators within a single TSSOP-16 package, delivering up to 1.6 A of output current per channel. The device operates from an input voltage range of 3.6 V to 25 V and supports adjustable output voltages starting from 0.8 V. Key electrical specifications include a switching frequency of 575 kHz and a quiescent current of 3.8 mA. It functions reliably across an extended temperature range from -40°C to +125°C junction temperature.

Feature Summary

• Dual integrated synchronous buck converters providing independent regulation channels
• Integrated power MOSFETs eliminate external switch requirements for simplified design
• Wide input voltage capability accommodates various supply sources
• Compact surface-mount packaging reduces board space consumption

Applications

• Portable equipment requiring multiple regulated voltage rails

Procurement Notes

Verify the specific suffix configuration against official Analog Devices documentation to ensure correct pinout and thermal characteristics. Confirm RoHS compliance status through manufacturer declarations. Cross-reference the datasheet revision history to validate parameter consistency. Ensure ordering details match the exact package variant required for your PCB layout constraints.

Selection Notes

Select this component when dual isolated or non-isolated buck outputs are required in a compact form factor. Evaluate thermal performance based on total power dissipation across both channels. Consider the fixed switching frequency for EMI filtering requirements. Compare input voltage ranges against available system supplies to ensure operational margins are maintained under all load conditions.

Part Context

This part belongs to the LT3506 family of dual synchronous buck converters. It shares core architectural features with other variants in the series but differs in package type and specific thermal ratings. The family is designed for applications requiring high efficiency and minimal external component count compared to discrete solutions.

Replacement Considerations

LT3506IFE#PBF serves as a direct equivalent with identical electrical specifications and pinout compatibility.
