LT3750EMS#TR

Specialized ICS Overview

The LT3750EMS#TR is a flyback capacitor charging controller manufactured by Analog Devices Inc., packaged in a 10-MSOP (Tape & Reel). It utilizes proprietary boundary mode control to efficiently charge large capacitors from a 3V to 24V input range. The device integrates primary-side sensing, eliminating the need for high-voltage output dividers, and features a 78mV current limit for precise peak switch current control. Designed for compact high-voltage applications, it supports fast charging cycles with integrated protection against overcurrent and overtemperature conditions.

Specialized ICS Feature Summary

• Proprietary boundary mode control reduces switching losses and transformer size
• Primary-side sensing eliminates external high-voltage output divider resistors
• 78mV precision current limit ensures accurate peak switch current regulation
• Wide 3V to 24V input voltage range accommodates various power sources

Specialized ICS Applications

• Professional camera flash systems
• RF security and inventory management systems
• High-voltage test equipment
• Industrial ignition and pulse laser power supplies

Specialized ICS Procurement Notes

Verify the Tape & Reel (TR) packaging suffix matches the required reel quantity for automated assembly lines. Confirm the 10-MSOP supplier device package dimensions align with PCB footprint specifications. Ensure the component grade meets project reliability standards before integration into production workflows.

Specialized ICS Selection Notes

Select this controller for applications requiring rapid charging of large capacitance values up to 1000V. The 10-MSOP package is suitable for space-constrained designs. Ensure the external N-channel MOSFET can handle the peak currents dictated by the 78mV sense threshold and the specific transformer turns ratio used for the target output voltage.

Specialized ICS Part Context

The LT3750 series addresses the limitations of discrete high-voltage charging solutions by integrating control logic and gate driving into a single IC. The EMS variant denotes the MSOP-10 package, while the #TR suffix indicates bulk tape-and-reel shipping. This component simplifies design by removing the need for secondary-side feedback loops across isolation barriers.

Specialized ICS Replacement Considerations

Direct pin-to-pin replacements are not explicitly documented in public datasheets. Evaluate alternative flyback controllers from Analog Devices or other manufacturers based on input voltage range, switching frequency compatibility, and package footprint constraints.
