Marvell Semiconductor Surprises with 88EM8183 LED Driver chip
Marvell Semiconductor www.marvell.com company would probably be the LAST company you name when selected a low end LED driver for a Triac-dimmable LED Bulb Design, but they have surprised quite a few people with their new 88EM8183 DRIVER IC. While their first entry into the highly competitive low margin driver market was the 88EN8080/8081 which was designed for single stage single string LED bulbs and the 88EN8801 designed for multiple string applications, they were relatively “me too” LED driver products.
Somebody has done their homework, however, as the new 88EM8183 is a study in the minimum external parts count to implement a leading edge (Triac) dimmable LED driver with the minimum parts count BoM. Check it out: Marvell-88EM8183-Product-Brief.pdf
