Product Overview

The LT3798EMSE#PBF is an Isolated Flyback Controller 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. Transformer specification and design is a critical part of successfully applying the LT3798. A tolerance of ±5% in turns ratio from transformer to transformer could result in a variation of more than ±5% in output regulation.
  • Isolated PFC flyback with minimum number of external components
  • VIN and VOUT limited only by external components
  • Active power factor correction
  • Low harmonic distortion
  • No opto-coupler required
  • Constant-current and constant-voltage regulation
  • Accurate regulated voltage and current (±5% typical)
  • Energy Star compliant (<0.5W no load operation)
