LTC3607IMSE#PBF

Voltage Regulators - DC DC Switching Regulators Overview

The LTC3607IMSE#PBF is a dual synchronous step-down DC/DC converter manufactured by Analog Devices Inc. It integrates two independent buck regulators within a single QFN-16 package. The device supports an input voltage range up to 15V and delivers up to 600mA per channel. It features a fixed switching frequency of 2.25MHz, adjustable output voltages from 600mV to 15V, and a low quiescent current of 55µA. The component operates across a temperature range of -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix #PBF indicates lead-free tape and reel packaging compliance with RoHS standards. Confirm that the IMSE designation corresponds to the industrial temperature grade (-40°C to +125°C). Ensure the QFN-16 package thermal pad connection requirements are addressed in the PCB layout design prior to procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when dual isolated or non-isolated buck outputs are required from a single 15V source. The 600mA per channel rating suits moderate load applications. Consider the 2.25MHz fixed frequency for noise-sensitive environments where synchronization is not required. Evaluate thermal dissipation needs due to the dense QFN-16 package configuration.

Voltage Regulators - DC DC Switching Regulators Part Context

The LTC3607 belongs to the LTC360x family of high-efficiency synchronous step-down converters. This series emphasizes compactness and performance for space-constrained designs. The IMSE variant specifically denotes the industrial temperature range extension compared to commercial grade options within the same product line.
