MaxLinear XRP6840 | Demoboard XRP6840EVB

Description

The XRP6840 is a controlled-current dual-cell supercapacitor charger and high power LED driver. Operating from a standard lithium-ion battery, the XRP6840 provides up to 4.3A of programmable Flash LED current and up to 600mA and 5.6V of programmable supercapacitor charging current and voltage.The XRP6840EVB, Exar’s XRP6840 Evaluation Board, supports either XRP6840A or XRP6840B in a 4x4 TQFN package and is fitted by default with the XRP6840A supporting three channels.With 1x, 1.5x and 2x charge pump operating modes, XRP6840EVB can provide a stable drive current for up to 3 1.5A, 4W Luxeon Flash LEDs. The evaluation board is a completely assembled and tested surface mount board which provides easy probe access points to all XRP6840 inputs and outputs for easy connection and measuring.
