Product details

100V supply rail — direct connection without pre-regulation

The LT3758EDD#PBF: The wide input also supports battery-powered applications where the voltage sags under load — the controller keeps running down to 5.5 V.

Boost, flyback, SEPIC — one IC for multiple topologies

The LT3758EDD#PBF supports boost, flyback, and SEPIC topologies, and its output can be configured as positive, negative, or isolated — a single BOM line covers a range of converter architectures without requalification.

Control features for sequencing and EMI shaping

Built-in Enable, Frequency Control, and Soft Start allow the designer to sequence the output ramp, synchronize the switching frequency to an external clock (Clock Sync = Yes), and spread the EMI spectrum by dithering the frequency.

Frequently asked questions

What is LT3758EDD#PBF's closest functional second-source?

The LT3758AIMSE#PBF is a functional peer with the same boost/flyback/SEPIC controller core, same 5.5 V to 100 V supply range, and same control features. The key difference is the package: the LT3758EDD#PBF comes in a 10-DFN (3×3 mm), while the LT3758AIMSE#PBF is in an MSOP-16. The pinout differs, so a board layout change is required to swap between them.

What compliance documentation does this part provide?

The LT3758EDD#PBF is ROHS3 Compliant per the lifecycle record. Standard compliance documentation (RoHS, REACH) is available from the manufacturer.
