LT3798EMSE#PBF Description

Short technical summary and product information.

The LT3798EMSE#PBF is an isolated flyback controller designed for offline applications requiring active power factor correction (PFC). This controller integrates PFC with no opto-coupler required for output voltage feedback, enabling single-stage conversion.

 

Key features include a wide input voltage range of 90V to 265V AC, with output voltage and current limited only by external components. Typical applications can achieve efficiencies higher than 86% with output power levels up to 100W. The device also boasts low harmonic distortion and meets Energy Star requirements with less than 0.5W no-load operation.

 

Packaged in a thermally enhanced 16-lead MSOP, the LT3798EMSE#PBF is suitable for various offline bus converter applications, including 12V, 24V, or 48V outputs, and high DC input isolated applications. Its design allows for a power factor greater than 0.97, ensuring compliance with harmonic current emission requirements.
