LT3970EDDB#TRMPBF

Overview

The LT3970EDDB#TRMPBF is a monolithic buck switching regulator from Analog Devices Inc., housed in a 10-DFN package. It accepts an input voltage range up to 40V and delivers a maximum output current of 350mA. The device features an adjustable switching frequency ranging from 200kHz to 2.2MHz, allowing for optimization of external component size and efficiency. Quiescent current consumption is specified at 2.5µA, supporting battery-powered applications. The internal switch is rated for continuous operation within the defined thermal and electrical limits.

Feature Summary

Adjustable switching frequency allows customization of external passive component sizes
Low quiescent current consumption supports extended battery life in portable designs
Wide input voltage range accommodates various power source configurations

Applications

Battery-powered portable electronics requiring low standby current
Industrial control systems with wide input voltage variations
Embedded systems needing compact DC-DC conversion solutions

Procurement Notes

Verify the specific suffix 'EDDB' against official Analog Devices documentation to confirm temperature grade and packaging details. Ensure compatibility with required thermal management strategies for the DFN package. Cross-reference ordering information directly with manufacturer datasheets to avoid discrepancies in pinout or electrical specifications during procurement.

Selection Notes

Select this component when design requirements include a wide input voltage range up to 40V combined with low quiescent current needs. Consider the adjustable frequency feature if minimizing inductor size is a priority. Evaluate thermal performance constraints inherent to the DFN package for the expected load conditions.

Part Context

This part belongs to the LT3970 family of high-voltage buck regulators designed for space-constrained applications. It shares core architecture with other variants in the series but differs in package type and specific electrical characteristics defined by the suffix. The family targets applications requiring efficient step-down conversion from higher voltage rails.
