LT3970EDDB-5#TRPBF

Overview

The LT3970EDDB-5#TRPBF is a monolithic buck switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 4.2V to 40V and provides a fixed output voltage of 5V at a maximum current of 350mA. The device features an adjustable switching frequency from 200kHz to 2.2MHz and consumes only 1.8µA of quiescent current in standby mode. It is housed in a 10-lead DFN package and supports operation temperatures from -40°C to +125°C.

Feature Summary

Adjustable switching frequency allows optimization for efficiency or component size
Ultra-low quiescent current minimizes power consumption during standby
Wide input voltage range accommodates various supply sources

Applications

Battery-powered portable equipment
Industrial control systems
Automotive electronics

Procurement Notes

Verify the specific suffix 'EDDB' against official Analog Devices documentation to confirm temperature grade and package details, as distributor listings may vary. Confirm RoHS compliance status directly with the manufacturer datasheet. Ensure the ordering part number matches the exact required pinout and thermal characteristics for your design.

Selection Notes

Select this component when a wide input voltage range up to 40V is required alongside low standby power consumption. The adjustable frequency feature enables designers to balance between electromagnetic interference filtering requirements and external component size constraints. Verify that the 350mA output current meets the load requirements of the target application circuit.

Part Context

This part belongs to the LT3970 family of high-voltage step-down switching regulators. Similar parts in the series include the LT3970IDDB and LT3970EMS variants, which share core electrical specifications but differ in package type (DFN vs MSOP) and operating temperature ranges. The family is designed for applications requiring efficient power conversion from higher voltage rails.
