LT3470IDDB#TRMPBF

Overview

The LT3470IDDB#TRMPBF is a micropower step-down DC/DC converter manufactured by Analog Devices Inc. It integrates a 300mA power switch, catch diode, and boost diode into an 8-pin DFN package measuring 3mm x 2mm. The device operates with an input voltage range of 4V to 40V and provides an adjustable output voltage from 1.25V to 16V. It delivers up to 200mA of output current while maintaining low quiescent current. The regulator combines Burst Mode operation with continuous conduction mode to minimize ripple and allow the use of small external components.

Feature Summary

Integrates a 300mA power switch, catch diode, and boost diode within a compact footprint
Combines Burst Mode and continuous operation for optimized efficiency across load ranges
Supports wide input voltage ranges suitable for various power supply architectures

Applications

Battery-powered portable equipment requiring low quiescent current
Space-constrained designs utilizing micro-power regulators
Systems requiring integrated inductor-less or small-component solutions

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors. Confirm package integrity upon receipt as surface-mount devices are sensitive to handling. Ensure storage conditions meet manufacturer specifications to prevent moisture damage prior to soldering. Cross-reference datasheet revisions to confirm pinout compatibility with existing designs.

Selection Notes

Select this component when design constraints require a small form factor combined with high input voltage tolerance. The integrated boost diode simplifies circuit topology compared to standard buck converters. Evaluate thermal performance requirements based on the DFN package's heat dissipation capabilities relative to expected load currents.

Part Context

This part belongs to the LT3470 family of micropower switching regulators. The IDDB suffix indicates an industrial temperature grade variant housed in a thin DFN package. This series is designed for applications demanding high efficiency and minimal external component count in space-limited environments.
