iWatt, Inc. (Los Gatos, CA) released two primary-side-regulated, leading- and trailing-edge-dimmable, AC/DC Digital PWM Controllers targeting 100V/230VAC offline LED lighting applications.

Designed for isolated or non-isolated LED drivers used in incandescent replacement lamps including both space-constrained (GU10, MR16) and larger (A, PAR) types, the iW3612 (3W to 25W) and low-power iW3602 (3W to 10W) incorporate features to ensure long life, power efficiency, reduced size and component costs, and flicker-free compatibility with existing wall dimmers worldwide.

Both LED driver ICs are pin compatible with the previous-generation iW3610, but offer wider dimmer compatibility and introduce new hot-plug support, where the user can swap the LED engine without recycling the input power for the LED driver.
