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 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.

DESCRIPTION Logic low on SD pin shuts down the Current Source completely and decreases current consumption to less than 1uA Logic high =PWM mode, logic low =PSM mode. In PSM mode synchronous rectification is disabled. Externally controlled synchronization signal. Logic high to low transition forces the clock synchronization. If not used must be connected to Vin or logic high. Input supply voltage Ground Included inside the package for fixed voltage. To be added externally for all self-selected voltages. Voltage test point. To test the minimum gap above VL. To be added externally for selected output current. Output current. LED connection

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.
