More and more, people are committed to find impactful ways to conserve energy in their homes and businesses. And yet simple solutions, such as LED lighting, have been cost-prohibitive, and thus out of reach for the mainstream consumer.
With Marvell`s (www.marvell.com) single-chip, unique mixed-signal LED driver architecture, lighting designers can more easily build energy-efficient, superior lighting features and controls into lower cost mainstream professional and consumer products, enabling more widespread adoption of eco-friendly LED lighting.
88EM8801The 88EM8801 device controls two LED strings using PWM current control. Intelligent digital control allows for 10bit PWM dimming resolution and up to 0.1% deep dimming capability. The incorporated OTP memory block further allows the calibration of each string to its respective target LED current, during the final light fixture manufacturing. As a result, the 88EM8801 device enables the mass production of consistent light output, without using tight, hence expensive, binning LEDs.
Moreover, the 88EM8801 device enables high quality light output in terms of warm CCT (correlated color temperature) and high CRI (color rendering index) by mixing red LEDs with cool white LEDs or bluish green LEDs. The 88EM8801 device integrates I2C compatible Two Wire Serial Interface (TWSI) which can connect with different communication units, such as ZigBee®, PLC, Wi-Fi or others, for dimming and on/off control, enabling further energy efficiency through networked lighting control.
Target ApplicationsThe 88EM8801 supports a wide range of applications from professional luminares to consumer light bulbs:
- Down lights and recessed lights - PAR lamps including PAR20, PAR30, and PAR38 - A lamps - MR, AR, and GU lamps - LED modules
