LT3506IDHD#PBF

Overview

The LT3506IDHD#PBF is a dual monolithic step-down switching regulator manufactured by Analog Devices Inc. It integrates two independent 1.6A buck converters in a single package, supporting an input voltage range of 3.6V to 25V. Each channel provides an adjustable output voltage from 0.8V to 23.25V. The device operates with a fixed switching frequency of 1.2MHz and utilizes a 16-lead DFN package with an exposed pad for thermal management.

Feature Summary

Dual integrated 1.6A synchronous buck converters
Wide input voltage range up to 25V
Adjustable output voltage down to 0.8V
Fixed 1.2MHz switching frequency

Applications

Industrial point-of-load regulation
Distributed power systems
Battery-powered equipment
Telecommunications infrastructure

Procurement Notes

Verify the specific suffix #PBF indicates leaded packaging when sourcing this component. Confirm the 'I' grade designation matches the required operating temperature range for your application environment. Cross-reference the manufacturer part number with authorized distributors to ensure authenticity and traceability before procurement.

Selection Notes

Select this component when dual isolated or non-isolated low-voltage rails are required from a higher voltage bus. The 1.2MHz frequency allows for smaller passive components compared to lower-frequency alternatives. Ensure the thermal design accommodates the power dissipation within the 16-lead DFN package constraints for reliable operation.

Part Context

This part belongs to the LT3506 family of dual step-down regulators. It shares functional similarities with other ADI buck controllers but offers a fully integrated solution with internal switches. The IDHD variant specifies the industrial temperature range and DFN package type, distinguishing it from commercial grade or different package options.
