LT3905IUD#PBF

Overview

The LT3905IUD#PBF is a boost switching regulator IC manufactured by Analog Devices Inc. It features an adjustable output voltage range starting from 1.248V up to 65V, with a maximum switch current of 350mA. The device operates within an input voltage range of 2.7V to 12V and supports a switching frequency between 1MHz and 2MHz. It provides a single positive output and is housed in a 16-WFQFN package with an exposed pad, suitable for surface mount installation across a temperature range of -40°C to 125°C.

Feature Summary

Boost topology with adjustable output capability
Integrated high-voltage switch rated for 65V
Wide input voltage operating range
Fixed-frequency operation with programmable synchronization

Applications

Battery-powered systems requiring step-up conversion
Industrial control power supplies
Automotive electronics applications
Portable instrumentation power management

Procurement Notes

Verify the suffix #PBF indicates lead-free RoHS compliance and tube packaging, distinct from the #TRPBF tape-and-reel variant. Confirm the I-grade designation matches required thermal performance specifications. Cross-reference the manufacturer part number directly with official Analog Devices documentation to ensure authenticity and correct revision level before procurement.

Selection Notes

Select this component when a compact boost solution is needed for inputs up to 12V. Ensure the load current does not exceed the 350mA switch limit. Verify that the required output voltage falls within the 1.248V to 65V adjustable range. Consider the 16-QFN package size constraints and thermal dissipation requirements for the specific application environment.

Part Context

This part belongs to the LT3905 family of high-efficiency boost regulators designed for space-constrained applications. It integrates a power switch and control circuitry into a small footprint. The family offers flexibility through adjustable output voltages and external compensation options, catering to diverse power conversion needs in industrial and automotive sectors.
