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 • Medical instrumentation • General and emergency/alarm lighting • Design and architectural lighting • Interior and runway lights • Outdoor accent lighting • Household appliances ORDERING INFORMATION FX FUNCTION SIZE CIRCUIT IDENTIFIER OUTPUT VOLTAGE - ADJ for adjustable version - self selectable output voltage.
