LT3999HMSE#PBF

Overview

The LT3999HMSE#PBF is a monolithic, high-voltage, high-frequency DC/DC transformer driver designed to provide isolated power in a small solution footprint. It operates as a push-pull switching regulator with an adjustable output and supports a single output configuration. The device accepts an input voltage range from 2.7V to 36V and delivers up to 1A of output current. It features a switch frequency range of 50kHz to 1MHz and functions within a junction temperature range of -40°C to 150°C. The component is housed in a 10-MSOP package with an exposed pad.

Feature Summary

Monolithic high-voltage design for compact isolated power solutions
Integrated duty cycle control functionality
High-frequency operation capability up to 1MHz

Applications

Low noise DC/DC transformer drivers
Isolated power supply generation
Electric vehicle fast charger infrastructure
Energy storage systems

Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance when sourcing. Confirm the MSOP-EP package dimensions against your PCB layout requirements. Ensure the input voltage does not exceed the 36V maximum rating during operation. Check for availability constraints as distribution status may vary by region.

Selection Notes

Select this component when a high-voltage push-pull topology is required for isolated conversion. It is suitable for applications needing adjustable output voltages with a maximum current of 1A. Consider the thermal performance of the exposed pad for heat dissipation. Verify that the operating frequency range aligns with the magnetic component specifications.

Part Context

This part belongs to the LT3999 family of DC/DC drivers manufactured by Analog Devices Inc. It is specifically engineered for driving transformers in high-frequency switching applications. The device integrates the necessary logic and drivers to simplify the design of isolated power stages compared to discrete solutions.
