DC1816B Offline Isolated Flyback LED Driver with PFC

DC1816B is a reference design for LED drivers, featuring LT®3799-1 controller, providing 3A constant current output 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.
