LT3686EDD#PBF

Overview

The LT3686EDD#PBF is a synchronous step-down switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 3.6 V to 37 V and delivers up to 1.2 A of output current. The device features a fixed 30 V maximum output voltage capability and supports adjustable switching frequencies between 300 kHz and 2.5 MHz. It utilizes a DFN-10 package for surface mount installation. The component functions within a temperature range of -40°C to +125°C, drawing a typical quiescent current of 1.1 mA during operation.

Feature Summary

Integrates high-efficiency synchronous power switches to eliminate external catch diodes
Supports wide input voltage ranges suitable for industrial applications
Features adjustable switching frequency for optimization of external component size

Applications

Industrial point-of-load regulation
Battery-powered equipment power management
General-purpose DC/DC conversion in compact systems

Procurement Notes

Verify the specific suffix #PBF confirms lead-free compliance and RoHS standards before integration. Confirm the DFN-10 package dimensions match the target PCB footprint. Ensure thermal design accounts for the specified operating temperature range. Validate that the 37 V input limit aligns with system supply conditions.

Selection Notes

Select this component when a single-output buck converter is required with inputs up to 37 V. The 1.2 A current rating suits moderate load applications. Consider the adjustable frequency feature if minimizing passive component volume is critical. Verify compatibility with the DFN-10 thermal pad requirements for adequate heat dissipation.

Part Context

This part belongs to the LT3686 series of monolithic buck regulators. It shares architectural similarities with other high-voltage step-down converters from Analog Devices but is distinct in its specific 1.2 A current limit and 37 V input ceiling. The EDD suffix denotes the specific DFN-10 package variant.
