LT3506AIFE#TRPBF

Overview

The LT3506AIFE#TRPBF is a dual monolithic step-down switching regulator manufactured by Analog Devices Inc. It integrates two independent current-mode PWM controllers with internal power switches, each capable of delivering up to 1.6 A of output current. The device operates from an input voltage range of 3.6 V to 25 V and provides adjustable output voltages between 0.8 V and 23.25 V. It features a fixed switching frequency of 1.1 MHz and a quiescent current of 3.8 mA. The component is housed in a 16-lead TSSOP package with an exposed pad and supports operation within a temperature range of -40°C to +85°C.

Feature Summary

Dual-channel architecture with synchronized oscillators operating in opposite phases to minimize input ripple current
Integrated high-side power switches rated for 1.6 A continuous output per channel
Current-mode control topology for rapid transient response and inherent cycle-by-cycle current limiting

Applications

Point-of-load regulation for digital signal processors and microcontrollers
Power distribution networks requiring multiple independent voltage rails
Battery-powered systems requiring efficient step-down conversion from single-cell sources

Procurement Notes

Verify the specific suffix #TRPBF confirms tape-and-reel packaging when ordering. Confirm the 'A' grade designation matches required performance specifications against standard variants. Ensure the 16-TSSOP footprint aligns with PCB layout constraints before finalizing procurement.

Selection Notes

Select this component when dual isolated outputs are required from a single controller unit. The 1.1 MHz frequency allows for smaller passive components compared to lower-frequency alternatives. Verify that the 1.6 A per-channel limit meets peak load requirements without exceeding thermal limits in the TSSOP enclosure.

Part Context

This part belongs to the LT3506 family of dual buck regulators. It shares functional similarities with the LT3506IFE but differs in packaging and manufacturing lot specifications. The series is designed for applications needing compact dual-rail power solutions without external driver complexity.
