LT3487EDD#PBF

Overview

The LT3487EDD#PBF is a dual-output step-up DC/DC controller designed for automotive applications. It operates with an input voltage range of 2.3V to 16V and supports output voltages from 1.23V to 28V. The device features a fixed switching frequency of 2150kHz and draws a maximum supply current of 3.7mA. It functions within an extended temperature range of -40°C to 85°C and is housed in a 10-pin DFN EP surface-mount package measuring 3mm x 3mm with a maximum height of 0.75mm.

Feature Summary

Dual-output step-up topology for simultaneous power generation
Automotive-grade design for vehicle environments
High-frequency operation enabling compact passive components

Applications

Automotive power systems
Dual-rail boost converter circuits
Vehicle electronics requiring isolated or separate high-voltage rails

Procurement Notes

Verify the specific suffix and tape/reel configuration against the manufacturer's official datasheet before ordering. Confirm that the component meets the required RoHS and REACH compliance standards for your region. Ensure the package dimensions match your PCB footprint exactly, as variations may exist between manufacturing lots.

Selection Notes

Select this controller when a dual-output boost solution is required for automotive systems. The 2150kHz frequency allows for smaller inductors compared to lower-frequency alternatives. Verify that the input voltage range covers your system's minimum operating conditions and that the thermal performance of the DFN EP package suits your enclosure constraints.

Part Context

This component belongs to the LT3487 family of dual-output step-up controllers manufactured by Analog Devices Inc. It is specifically engineered for automotive environments, distinguishing it from general-purpose industrial regulators. The part integrates control logic for two independent boost channels within a compact thermally enhanced package.
