Santa Clara, Calif. -- Marvell has added two new smart digital LED driver integrated circuits (ICs) – the 88EM8189 and 88EM8803 – expanding its end-to-end smart lighting platform into LED lamps and fixtures. The 88EM8189 is touted as the industry's first smart AC/DC LED controller that offers Inter-Integrated Circuit (I2C) control interface, integrated standby power supply for networking circuit and backward compatibility with legacy dimmers. Together with Marvell’s ZigBee 88MZ100 controller, the 88EM8189 enables a low bill of materials (BOM) for smart wireless LED bulbs, at an affordable price point, that is expected to accelerate consumer adoption of smart lighting.
The 88EM8803 is the second generation chip based on the Marvell's intelligent DC/DC dual-channel LED controller, the 88EM8801. It offers a wide LED output range up to a maximum of 60V, 1A for each channel. The 88EM8803 integrates an I2C interface for wireless lighting control and low-side switches to provide low BOM cost, reducing design complexity for various lighting applications, including linear tubes, high color rendering index (CRI), warming dimming or color temper tunable lamps that require multi-string LEDs.
The 88EM8189 driver chip is said to achieve the smallest driver footprint and lowest system cost to provide smart lighting for all form factor LED lighting applications, ranging from A, BR, PAR lamps to smaller GU10 and E17 bulbs. The 88EM8803 chip can be used in commercial and residential lighting applications where multiple string of LEDs are used, for example, linear tubes and troffers replacement, LED modules, warming dimming and color temperature tunable lamps. Both LED controllers provide ease of design, excellent dimming performance while significantly reducing cost of LED driver electronics, thanks to the innovations in chip architecture, said Marvell.
