Chip gives dim-to-warm LED lighting without MCU
To simplify incandescent-like LED dimming – where colour temperature (CCT) falls with intensity – Dialog Semi has introduced a single chip dual output power converter that needs no microcontroller. iW3640 is a 25W 2-channel mains-powered LED driver, intended for 75-150W-equivalent A19 and PAR bulbs, as well as 20-45W commercial dimmable external lighting ballasts. It works […]
