LT3800IFE#PBF

Overview

The LT3800IFE#PBF is a high-voltage synchronous current mode step-down switching regulator controller manufactured by Analog Devices Inc. It operates with a fixed switching frequency of 200kHz and supports an input voltage range from 4V to 60V. The device features a single output configuration with one phase, designed for efficient power management in demanding applications. It utilizes a 16-TSSOP-EP package for surface mount installation. The controller includes enable functionality and supports both positive and negative output configurations. Operating temperatures range from -40°C to +125°C TJ.

Feature Summary

Synchronous current mode architecture for high efficiency
High voltage operation up to 60V input
Fixed 200kHz switching frequency
Integrated enable control feature

Applications

Industrial power supplies
Telecommunications equipment
Distributed power systems

Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and RoHS3 status when ordering. Confirm the TSSOP-EP package variant matches your PCB footprint requirements. Ensure the supplier provides valid manufacturer traceability documentation. Check for any recent product change notices regarding epoxy or material declarations before finalizing procurement plans.

Selection Notes

Select this component for designs requiring high input voltage capability with synchronous rectification benefits. The fixed 200kHz frequency allows for optimized passive component sizing. Consider the thermal performance of the exposed pad package for heat dissipation needs. Verify that the external N-channel MOSFETs selected are compatible with the gate drive characteristics provided by this controller.

Part Context

This part belongs to the LT3800 series of high-voltage DC/DC controllers. It is designed as a standalone controller rather than an integrated converter, allowing flexibility in power stage design. The device complements other Linear Technology power management solutions by providing precise current mode control for buck topologies.
