LTC3810IUH-5#PBF

DC DC Switching Controllers Overview

The LTC3810IUH-5#PBF is a synchronous step-down DC/DC controller from Analog Devices, designed for high-voltage input applications up to 60V. It utilizes a constant on-time valley current mode architecture to achieve low duty cycle and fast transient response without requiring a sense resistor. The device features an integrated LDO for gate drive power, independent TRACK/SS pins for synchronized startup, and current foldback protection. It operates within a temperature range of -40°C to +125°C and is housed in a 32-lead QFN package.

DC DC Switching Controllers Procurement Notes

Verify the specific suffix 'IUH-5' against official Analog Devices documentation to confirm the exact temperature grade and package variant. Ensure compatibility with external MOSFETs regarding voltage ratings and gate drive requirements. Cross-reference the datasheet for any recent design revisions or obsolescence notices prior to finalizing procurement plans.

DC DC Switching Controllers Selection Notes

Select this component when a high-voltage input (up to 60V) synchronous buck controller is required. The constant on-time architecture suits applications needing fast transient response and low duty cycle operation. Consider the integrated LDO simplifies biasing but requires sufficient VIN headroom. Evaluate thermal performance based on the QFN package and expected load currents.

DC DC Switching Controllers Part Context

This part belongs to the LTC3810 family of high-performance synchronous step-down switching regulator controllers. It is engineered for efficiency and robustness in demanding environments. The 'IUH-5' designation indicates a specific industrial temperature grade and package configuration within the broader product line, sharing core control logic with other variants like the EG version.
