DESCRIPTION

· Ideal for single-stage PFC constant current LED bulbs and downlighters.
· Incorporates high-voltage power MOSFET and variable frequency controller.
· Built-in TRIAC detector for leading-edge and trailing-edge dimmers.
· Advanced thermal management and comprehensive protection features.
· Low-side switching topology for low EMI and reduced input filter size.

FEATURES

· Combined single-stage PFC and accurate CC output.
· Power Factor >0.9, THD as low as 7% in optimized designs.
· Advanced TRIAC dimmer detection and selectable dimming profile.
· Fast turn-on (<500 ms), low pop-on, and dead-travel.
· Supports multiple topologies: buck, boost, flyback, etc.
· Up to 20 W output, no electrolytic bulk capacitors or optoisolators.
· Comprehensive protection: OVP, short-circuit, thermal foldback.

APPLICATIONS

· LED bulbs and downlighters with TRIAC dimming.
· Isolated and non-isolated flyback topologies.
· Open frame designs with adequate heat sinking.
· Cost-optimized designs with EcoSmart switching technology.
