LT3470EDDB#TRMPBF
Overview
The LT3470EDDB#TRMPBF is a Micropower Buck Regulator designed for high efficiency over a wide range of input voltages from 4V to 40V. It integrates both the boost and catch diodes into a compact 3mm x 2mm DFN package, minimizing external component count for space-constrained designs. The device utilizes Burst Mode operation to maintain low quiescent current at light loads, making it ideal for battery-powered systems requiring standby efficiency.
Why Choose This Part
This regulator features integrated boost and catch diodes, significantly reducing the PCB area and bill-of-materials complexity. Its low 18uA quiescent current and 0.5uA shutdown current are critical for maximizing uptime in battery-operated electronics.

Key Specifications
Getting Started
Designers should prioritize placing the input capacitor and the VOUT feedback resistors close to the IC to minimize noise and improve regulation. Evaluation of the design can be performed using the Analog Devices DC992A demonstration board, which highlights the LT3470's ability to drive up to 200mA from 40V inputs.
