LT3970EMS#TRPBF

Overview

The LT3970EMS#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 delivers up to 350mA output current. The device features an adjustable switching frequency from 200kHz to 2.2MHz and consumes only 1.8µA of quiescent current. It utilizes a 10-lead MSOP package with exposed pad for surface mount installation.

Feature Summary

Adjustable switching frequency allows optimization for efficiency or component size
Ultra-low quiescent current supports extended battery life in portable applications
Integrated Schottky diode simplifies external component requirements

Applications

Battery-powered portable equipment
Industrial control systems
Automotive electronics

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm the EMS package variant matches your PCB footprint requirements. Check current availability status as supply may be limited. Ensure RoHS compliance documentation aligns with regional regulatory standards for your manufacturing facility.

Selection Notes

Select this part when input voltages exceed standard low-voltage regulators but remain below higher voltage thresholds. The adjustable frequency feature enables trade-offs between inductor size and electromagnetic interference. Consider thermal performance due to the exposed pad design for adequate heat dissipation in compact enclosures.

Part Context

This component belongs to the LT3970 family of high voltage step-down converters. It shares core architecture with variants like LT3970IDDB and LT3970IMS, differing primarily in package type and temperature rating specifications. The series targets applications requiring wide input voltage ranges with minimal standby power consumption.

Replacement Considerations

LT3970EMS-5#TRPBF offers fixed 5V output instead of adjustable. LT3970IDDB-3.3#TRPBF provides DFN-10 packaging alternative. Verify pin compatibility and thermal characteristics before substituting different package options within the same product family.
