STEVAL-ILL084V1:0.5 A, floating boost LED driver board based on the LED6000

The STEVAL-ILL084V1 product evaluation board is based on the LED6000 monolithic current source for high power LED driving. The floating boost topology can benefit from the LED6000 wide input voltage range to drive many power LED in series. The LED6000 is a 61 V asynchronous switching regulator with embedded power MOSFET, designed to supply up to 3 A DC currents depending on the application conditions. The 250 mV typical RSENSE voltage drop, embedded switch-over feature on the VBIAS pin and light load management (pulse skipping) maximize power conversion efficiency across the entire load range. Digital dimming is implemented by driving the dedicated DIM pin.

The current limit threshold and the switching frequency are adjustable for application optimization. The device includes an internal 250 kHz oscillator that can be externally adjusted up to 1.5 MHz. The size of the overall application is minimized thanks to the high switching frequency and its compatibility with ceramic output capacitors. Two LED6000 regulators can be synchronized in a 180° out-of-phase configuration for reduced total input RMS current.
