LT3693IMSE#PBF

Overview

The LT3693IMSE#PBF is a monolithic synchronous step-down switching regulator manufactured by Analog Devices Inc. It accepts input voltages up to 36V and delivers an adjustable output voltage ranging from 0.79V to 30V with a maximum output current of 3.5A. The device operates at a programmable switching frequency between 230kHz and 2.45MHz. It features a 10-TFSOP, 10-MSOP package with an exposed pad for thermal dissipation. The component supports operation across a junction temperature range of -40°C to 125°C.

Feature Summary

Integrates high-efficiency internal power switches to eliminate the need for external catch diodes
Supports flexible design through user-programmable switching frequencies
Includes built-in soft-start circuitry to limit inrush current during startup

Applications

Point-of-load regulation for industrial equipment
Power supply stages for telecommunications infrastructure
Voltage regulation for embedded computing systems

Procurement Notes

Verify the specific suffix against official documentation to confirm pinout compatibility and electrical specifications. Ensure the procurement channel provides valid traceability for the Analog Devices Inc. manufacturer. Confirm that the package type matches the required PCB footprint before finalizing orders.

Selection Notes

Select this component when a wide input voltage range up to 36V is required alongside high output current capabilities. The adjustable frequency feature allows optimization for size or efficiency constraints. Verify that the thermal performance of the MSOP package meets the application's heat dissipation requirements under full load conditions.

Part Context

This part belongs to the LT3693 family of synchronous buck regulators designed for applications requiring high efficiency and compact solutions. It serves as a direct replacement for legacy non-synchronous designs while offering improved performance metrics. The component is widely utilized in scenarios demanding reliable DC-DC conversion within constrained physical spaces.
