The LT3798 is a constant-voltage/constant-current isolated flyback controller that combines active power factor correction (PFC) with no opto-coupler required for output voltage feedback into a single-stage converter. A LT3798 based design can achieve a power factor of greater than 0.97 by actively modulating the input current, allowing compliance with most Harmonic Current Emission requirements.
The LT3798 is well suited for a wide variety of off-line applications. The input range can be scaled up or down, depending mainly on the choice of external components. Efficiencies higher than 86% can be achieved with output power levels up to 100W. In addition, the LT3798 can easily be designed into high DC input applications.
Applications
- Offline 5W to 100W+ Applications
- High DC VIN Isolated Applications
- Offline Bus Converter (12V, 24V or 48V Outputs)
At least one model within this product family is in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist.
