Dimmable LED Driver Provides a Low Cost Driver Solution for Dimmable LED Light Bulbs/Tubes

Supertex, manufacturer in high voltage analog and mixed signal integrated circuits (ICs),  introduced PS30, a constant frequency (67kHz), constant duty cycle LED driver optimized for dimmable off-line LED bulb/tube applications, providing high power factor correction (PFC). PS30 is intended to drive a single switch, single inductor power converter (flyback for isolated version and buck-boost for non-isolated version) directly from AC line, 110V or 220V, for power levels up to 20W. PS30DB1 demo board provides a 6.3W design solution, achieving 93% PFC and greater than 81% efficiency with +/-4% current accuracy. It can be modified for other power levels up to 20W.
