LT3800EFE#TRPBF

Overview

The LT3800EFE#TRPBF 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 16-TSSOP-EP package with exposed pad for thermal management. It provides one output configured as a transistor driver, suitable for positive or negative output applications. The controller includes enable control characteristics and functions as a buck topology converter. Operating temperature ranges from -40°C to 125°C TJ.

Feature Summary

Synchronous current mode control architecture for high efficiency
High voltage input capability up to 60V
Integrated internal VCC regulator for simplified startup
Reverse current inhibition protection

Applications

Industrial power supplies
Point-of-load conversion modules
Telecommunications infrastructure equipment
Automotive electronics systems

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging versus #PBF tube packaging when ordering. Confirm the exact component marking matches the datasheet specifications. Ensure the supplier provides valid RoHS compliance documentation. Check lead times as availability may vary. Validate that the received part number corresponds exactly to the requested model before integration into designs.

Selection Notes

Select this controller for applications requiring high input voltages and synchronous rectification. Consider the 200kHz fixed frequency for inductor sizing. Evaluate thermal performance due to the TSSOP-EP package. Compare against non-synchronous alternatives for efficiency requirements. Ensure gate drive capabilities match the external N-channel MOSFETs selected for the design.

Part Context

The LT3800 belongs to Analog Devices' family of high-voltage DC/DC controllers. It complements other Linear Technology products designed for robust power management. The device addresses needs for efficient step-down conversion in harsh environments. It serves as a core component in complex power distribution networks.
