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.
> 300mA. 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 ultra-high
efficiency, the Power LED Driver is designed to operate in
synchronous rectified PWM mode under full load while
transforming into externally controlled pulse-skipping mode
(PSM) under light load (e.g. for LED’s with 20 to 200mA).
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 - 40°C to 85°C.
APPLICATION
Bike lamps
Headlights and flashlights
