Exar Corporation is Powering Connectivity by delivering highly differentiated silicon, software and subsystem solutions to secure and optimize data for storage and transmission across traditional and packet-based networks. A comprehensive knowledge of end-user markets along with the underlying analog and digital technologies allows Exar to offer innovative solutions to customers in a wide range of markets from enterprise and SMB, to consumer and industrial.

The XRP7603EVB Evaluation Board is a related product complementing  the XRP7603 device which is a non-synchronous voltage mode PWM step down converter optimized to drive a string of high power LEDs at up to 500 mA of continuous current. The device has a wide 4.5 V to 29 V input voltage range allowing for single supply operations from industry standard 5 V, 12 V or 24 V power rails. The XRP7603 is pin-to-pin compatible with Exar’s XRP7604 and SP7600 devices providing the most flexibility when designing evolutive and scalable lighting solutions from 500 mA to 2 A and is offered in a compact thermally enhanced lead free RoHS compliant 8-pin SO package.

The XRP7603 is a non-synchronous voltage mode PWM step down converter with integrated high side FET optimized to drive high power LEDs at up to 2 A of continuous current.
