LT3470HTS8#TRPBF

Overview

The LT3470HTS8#TRPBF 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 a TSOT-23-8 package. 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 with a switching frequency of 1.2MHz. Quiescent current is specified at 25uA. The component supports operation temperatures from -40°C to +150°C.

Feature Summary

Integrates a 300mA power switch, catch diode, and boost diode within a compact TSOT-23-8 package.
Combines Burst Mode and continuous operation to enable the use of miniature inductors and capacitors.
Provides low ripple output suitable for sensitive loads while maintaining high efficiency.

Applications

12V Step-Down Converter circuits
3.3V Step-Down Converter circuits
Micropower Buck Regulator designs

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm the HT grade meets thermal requirements for your application environment. Check manufacturer documentation for RoHS compliance status and lead time variations based on region. Ensure compatibility with standard surface mount assembly processes for TSOT-23-8 packages.

Selection Notes

Select this component for applications requiring wide input voltage ranges up to 40V in small form factors. It is suitable for battery-powered systems due to low quiescent current. Consider the 200mA output limit and 1.2MHz switching frequency when designing passive components. Evaluate thermal performance given the high maximum junction temperature rating.

Part Context

This part belongs to the LT3470 series of micropower buck regulators from Analog Devices. It is designed for space-constrained portable electronics and industrial applications requiring efficient voltage conversion from higher voltage rails to lower logic or sensor voltages.
