LT3999HMSE#TRPBF

Overview

The LT3999HMSE#TRPBF is a push-pull transformer driver IC designed for isolated DC-DC converter applications. It operates with an input voltage range from 2.7V to 36V and delivers a peak output current of 1A. The device supports adjustable switching frequencies between 50kHz and 1MHz, enabling optimization for efficiency and component size. It features a wide operating junction temperature range from -40°C to 150°C and is housed in a 10-MSOP-EP package.

Feature Summary

Push-pull topology optimized for driving isolated transformers
Adjustable switching frequency for design flexibility
Wide input voltage compatibility for various power sources

Applications

Isolated DC-DC converter designs
Flyback and forward converter topologies
Industrial power supply systems

Procurement Notes

Verify the specific suffix TRPBF indicates tape and reel packaging when sourcing components. Confirm that the HMSE grade meets the required thermal and electrical specifications for the intended operating environment. Ensure the 10-MSOP-EP footprint matches the PCB layout requirements before finalizing procurement orders.

Selection Notes

Select this component for applications requiring a dedicated push-pull driver rather than a complete regulator. Consider the 1A peak current capability against the transformer primary winding requirements. Evaluate the 36V maximum input limit to ensure compatibility with the system's power rail. Verify that the external transformer and feedback network can support the adjustable frequency range.

Part Context

This part belongs to the LT3999 family of transformer drivers manufactured by Analog Devices. It serves as a core control element for creating isolated power stages. The device complements other PMIC solutions by providing the necessary gate drive signals for high-side and low-side switches in transformer-based architectures.
