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

Demonstration circuit 1817B is an off-line isolated flyback converter featuring the LT®3798. The demo board provides a single constant-voltage output of 24V at 2A. It is optimized to operate over a wide AC input voltage range (90VAC to 265VAC, 47Hz to 63Hz). Output voltage accuracy stays within ±5% over the whole input voltage and load range. It provides a high power factor (>0.95) enabling the design to be used worldwide. It is also designed to comply with the IEC 61000-3-2 Class D harmonics standard and the EN55015B conducted EMI standard. The LT3798 controls an isolated flyback converter in boundary mode, suitable for applications with voltage or current regulation. Its novel sensing scheme delivers a PERFORMANCE SUMMARY well regulated output voltage or current to the secondary side without the use of an opto-coupler. The LT3798 is available in a low profile, thermally enhanced 16-lead MSOP package. The LT3798 data sheet gives a complete description of the part, operation and application information. The data sheet must be read in conjunction with this quick start guide for demo circuit 1817B.
