LTC3372HUK#PBF

DC DC Switching Controllers Overview

The LTC3372HUK#PBF is a synchronous step-down switching controller from Analog Devices, designed for high-voltage applications with an input range of 4.5V to 60V. It integrates five independent buck channels capable of delivering up to 8A per output. The device supports adjustable switching frequencies between 1MHz and 3MHz and features low quiescent current operation. Packaged in a 48-lead QFN (7x7mm) housing, it operates within a temperature range of -40°C to +125°C.

DC DC Switching Controllers Feature Summary

• Integrates five isolated synchronous buck controllers on a single chip
• Supports wide input voltage ranges up to 60V
• Features configurable switching frequencies for optimized efficiency
• Includes low quiescent current modes for standby power savings

DC DC Switching Controllers Applications

• Automotive electronics operating in harsh environments

DC DC Switching Controllers Procurement Notes

Verify the specific suffix 'H' indicates the extended industrial temperature grade (-40°C to +125°C) as defined by Analog Devices. Confirm package compatibility with the 48-lead QFN footprint during PCB layout. Ensure supply chain sources provide original manufacturer documentation to validate authenticity and traceability.

DC DC Switching Controllers Selection Notes

Select this component when designing systems requiring five distinct isolated outputs from a single high-voltage source. Compare against the LTC3372EUK#PBF if lower temperature ratings are acceptable. Evaluate thermal management needs due to the high current density in the QFN package. Verify that the external MOSFET selection matches the controller's drive capabilities.

DC DC Switching Controllers Part Context

This part belongs to the LTC3372 family of highly flexible multioutput power supply regulators. It complements other Analog Devices PMICs like the LTC3370 and LTC3374, offering a specialized solution for complex power architectures. The series focuses on reducing board space and component count in high-density designs.

DC DC Switching Controllers Replacement Considerations

The LTC3372EUK#PBF serves as a direct functional substitute with identical electrical specifications but may differ in temperature rating or packaging lot details. Verify pinout compatibility before substitution.
