LT3999EMSE#PBF

Overview

The LT3999EMSE#PBF is a monolithic push-pull DC/DC transformer driver manufactured by Analog Devices Inc. It operates with an input voltage range from 2.7V to 36V and delivers a continuous output current of 1A. The device supports adjustable switching frequencies between 50kHz and 1MHz, enabling the use of small external passive components. It features duty cycle control for ΔVin compensation to maintain regulation across wide input variations. The component is housed in a 10-lead MSOP package with an exposed pad and functions within a junction temperature range of -40°C to 150°C.

Feature Summary

Push-pull topology providing inherent low-noise isolated power generation
Duty cycle control for ΔVin compensation to minimize LDO losses
Wide input voltage range supporting diverse system requirements
Small solution footprint enabled by high-frequency operation

Applications

Medical instruments requiring low-noise isolated supplies
Industrial sensing and control systems
Data conversion equipment
Wide band communications infrastructure

Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and RoHS adherence before procurement. Confirm the 10-MSOP-EP package dimensions match the target PCB layout. Ensure the design accounts for the thermal performance requirements associated with the exposed pad ground connection for optimal heat dissipation during operation.

Selection Notes

Select this component when an isolated, low-noise power supply is required for sensitive analog or RF circuits. The push-pull architecture is suitable for applications needing galvanic isolation without complex control loops. Consider the 1A output capability and the flexibility of the adjustable frequency range when sizing external magnetics for specific voltage and current targets.

Part Context

This part belongs to the LT3999 family of high-voltage, high-frequency DC/DC transformer drivers. It is designed to drive push-pull transformers efficiently while maintaining a compact physical size. The series is characterized by its ability to handle wide input voltage ranges and provide stable isolated outputs through integrated duty cycle compensation mechanisms.
