描述
The iW3637 high-voltage, second-stage buck LED driver provides constant current to LEDs directly from DC power supplies. It supports non-isolated buck and flyback converter topologies to post-regulate from a PFC AC/DC boost converter, minimizing low-frequency output ripple current and eliminating virtually all flicker in the system, even down to 1%.
A wide range of DC input voltages simplifies design by enabling the use of just one second-stage driver across any commercial lighting product portfolio.
