ORDERING INFORMATION
The Power LED Driver is dedicated for optimum
performance to drive Power LED's. FX5959 is a complete
system solution for all Power LED's with high current for
e.g. > 300 mA. The driver provides a constant current
without exceeding the applicable LED voltage to ensure the
specified LED load life time. The integrated Current Source
provides flexibility of utilizing various battery
configurations and chemistries such as NiCd, NiMH, or Li+
with input voltage range of 2.5v to 6v. An additional
flexibility is provided by using external resistors to adapt to
various voltage input levels and LED configurations. For ul-
tra-high efficiency, the Power LED Driver is designed to op-
erate in synchronous rectified PWM mode under full load
while transforming into externally controlled pulse-skipping
mode (PSM) under light load (for e.g. LED's with 20 to 200 mA).
The FX5959 Current Source is available in 25-ports BGA
package. In order to satisfy the stringent ambient
temperature requirements, the Current Source is designed
to handle the industrial temperature range of 40C to 85C.
