DC1816B - LT3799EMSE-1 Demo Board I Offline Isolated Flyback LED Driver with PFC, 90VAC ≤ VIN ≤ 305VAC, Vout = 36V(nom) @ 3A

Demonstration circuit 1816B is an off-line isolated flyback LED driver featuring LT®3799-1. The demo board provides a single constant current output of 3A over an LED string voltage from 22V to 38V. It is optimized to operate over a wide AC input voltage range (90VAC to 305VAC, 47Hz to 63Hz). LED current typically stays within ±5% over the whole input voltage range. It provides a high power factor (>0.9) enabling a single design to be used worldwide. It is also designed to comply with the IEC 61000-3-2 Class C harmonics standard and the EN55015B conducted EMI standard.
