Overview
The LT3758EMSE is a high input voltage DC/DC controller from Analog Devices, designed for boost, flyback, SEPIC, and inverting topologies. It operates within an input voltage range of 5.5 V to 100 V and supports switching frequencies between 100 kHz and 1 MHz. The device features current mode control with a typical quiescent current of 1.75 mA. It provides one output channel capable of generating positive or negative voltages, including isolated outputs. The component is housed in a 10-MSOP-EP package and functions reliably across a temperature range of -40°C to +125°C.
Feature Summary
- Supports multiple converter topologies including boost, flyback, SEPIC, and inverting configurations.
- Enables generation of positive, negative, or isolated output voltages.
- Integrates clock synchronization capability for multi-phase or parallel operation.
- Includes control features such as enable pin, frequency control, and soft start.
Applications
- Industrial power supplies requiring wide input voltage ranges
- Automotive electronics systems
- Telecommunications infrastructure equipment
- Battery-powered devices with high voltage requirements
Procurement Notes
Verify the specific suffix (e.g., #TRPBF vs #PBF) to ensure correct packaging format, such as tape and reel versus tube. Confirm RoHS compliance status through official documentation. Ensure the ordering part number matches the exact package variant required for your PCB layout. Cross-reference the manufacturer's latest datasheet for any design changes or obsolescence notices before finalizing procurement.
Selection Notes
Select this controller when a wide input voltage range up to 100 V is required for non-isolated or isolated applications. Consider the 10-MSOP-EP package for space-constrained designs needing exposed pad thermal performance. Evaluate the need for clock synchronization if operating in parallel configurations. Ensure the external components support the desired switching frequency range of 100 kHz to 1 MHz.
Part Context
The LT3758 belongs to Analog Devices' line of high-voltage DC/DC controllers. It is part of the LT3758 series, which includes variants like the LT3758A. The EMSE designation indicates the MSOP-EP package type. This component serves as a core control IC for designing efficient power conversion stages in various industrial and commercial applications.
