LT3693EMSE#PBF

Overview

The LT3693EMSE#PBF is a 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 management. The component supports a wide operating temperature range from -40°C to 125°C TJ.

Feature Summary

Integrates high-efficiency synchronous power switches to eliminate external catch diodes
Supports programmable switching frequency for optimization of external component size
Includes internal compensation and soft-start circuitry for simplified design

Applications

Industrial point-of-load regulation
Distributed power systems
Battery-powered equipment

Procurement Notes

Verify the specific suffix #PBF indicates tube packaging rather than tape and reel when sourcing. Confirm the 'E' grade meets the required industrial temperature specifications. Cross-reference the manufacturer part number directly with official Analog Devices documentation to ensure authenticity and correct revision status before procurement.

Selection Notes

Select this component when a 36V input range and 3.5A continuous current are required in a compact MSOP footprint. The adjustable frequency feature allows designers to balance efficiency against EMI requirements. Ensure adequate thermal relief on the PCB due to the exposed pad requirement for heat dissipation during high-current operation.

Part Context

This part belongs to the LT3693 family of monolithic buck regulators designed for high-density applications. It shares architectural similarities with the LT3680 but offers specific performance characteristics tailored for general-purpose DC-DC conversion. The device integrates the control logic, oscillators, and power switches into a single small outline package.
