Power LED Driver the Smallest and Low Profile,
Constant Current Source 0 - 2.0A, 2.5V to 7V, with 450W/in3
Power Density and High Efficiency
FEATURES
• Fully integrated Power LED driver
• High efficiency over large load range
• 100% duty cycle
• Power density - more than 450W/inch3
• 1µA shutdown current
•
Variable input voltage 2.5V to 6V (1Li+ or 3-cell NiCd or NiMH cells)
• Controlled output current
• Programmable PWM/PSM controls
• Low output ripple
• BGA construction
• Temperature range: - 40°C to + 85°C
• No external components required
• Output power 15W
• Maximum current 2.5A
• Short circuit protection
• Low profile
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.
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).

DEMONSTRATION BOARD
TEST SET-UP AND OPERATION
Pins SD (Shut Down), PWM and SYNC (Synchronization) are
internally connected on the demo board to Vin.
1. Connect the DB according to the circuit drawing below
without connecting the LED
2. Use DC power supply, with current capability of twice the
output current.
3. Adjust VTP with R1 trimmer to a typical voltage of 0.6V above
the VL (LED voltage).
4. Connect the LED or equivalent resistor value according to
the circuit drawing below and adjust R0 trimmer to the
required current.
5. Input voltage can be adjusted between 2.5V to VTP.

SOLDERING PROFILE
All of the components must be dried prior to assembly as follows:
1.Samples and package type B1 and B5, bulk components - the recommended drying process is to be done at 125°C for 48 hours.
2. For package type T1 and T2 - per JEDEC J-STD-033 level5.
For taped components the recommended drying process is to be done at maximum 70°C.
