Marvell 40Watt 2-Stage, 4-Channel Smart External LED Driver

Marvell 40Watt 2-Stage, 4-Channel
Smart External LED Driver Reference Design
For Evaluation of the Marvell 88EM8042 and 88EM8801
LED Driver ICs
PRODUCT OVERVIEW
Marvell® offers a 40Watt 2-Stage, 4-Channel Smart External LED Driver Reference Design that is a turnkey
manufacturing-ready kit for commercial lighting applications. Supporting designs up to 40 Watts, the reference design
can be used for the development of commercial lighting fixtures, such as panel lights or troffers, that independently
control four strings of LEDs. It has been designed in a modular fashion to allow end users to develop products that
meet various lighting control requirements. The basic kit includes the 40Watt Marvell 88EM8042 Base Board and two
Marvell 88EM8801 modules encased in housing, plus a Quick Start Guide, User Manual, design files, transformer
specification and test reports. This base configuration is specified for Universal Input Voltage and four LED outputs
(30VDC/500mA) and supports 0-10V dimming down to five percent.
More functionality can be achieved with the addition of the optional modules which plug into the base board: 0-10V
two-wire dimming module, DALI network module or ZigBee (RF) wireless network module. The addition of these
modules, which support the latest industry standards, can be used for dimming down to one percent, smart lighting
control including on/off control, occupancy sensors, CCT tuning or color management.
For design flexibility, the Marvell 88EM8801 module may be purchased separately for use in custom configurations.
Designed with Marvell’s innovative mixed-signal architecture, the Marvell 88EM8042 IC delivers high power factor, high
efficiency, low total harmonic distortion and supports a wide range Universal input voltage. The highly integrated,
highly-efficient, Marvell 88EM8801 is the industry’s first intelligent LED driver to independently control two strings of
LEDs with digital interfaces.
