LT3470HTS8#TRMPBF

Overview

The LT3470HTS8#TRMPBF 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 quiescent current of 25uA. The switching frequency is fixed at 1.2MHz, and it functions within a temperature range of -40°C to +150°C.

Feature Summary

Integrates a 300mA power switch, catch diode, and boost diode for compact design
Combines Burst Mode and continuous operation for low ripple output
Supports high input voltages up to 40V in a small footprint

Applications

12V Step-Down Converter circuits
Battery-powered portable devices requiring high efficiency
Automotive electronics operating within specified voltage ranges

Procurement Notes

Verify the specific suffix TRMPBF against official Analog Devices documentation to confirm tape and reel packaging and lead-free status. Ensure compatibility with required thermal management solutions given the TSOT-23-8 package size. Cross-reference the datasheet for any recent revisions that may impact pinout or electrical characteristics before finalizing procurement specifications.

Selection Notes

Select this component when designing space-constrained systems requiring a wide input voltage range up to 40V. It is suitable for applications needing integrated boost and catch diodes to minimize external component count. Consider the 1.2MHz switching frequency for balancing inductor size against transient response requirements.

Part Context

This part belongs to the LT3470 series of micropower buck regulators. It shares the core architecture with variants like LT3470EDDB and LT3470HTS8#TRPBF, differing primarily in packaging and shipping configuration. The series is designed for high-efficiency power conversion in small form factors.
