The STEVAL-ILL088V1 evaluation board is based on a monolithic current source for high power LED driving, the LED6000, a 61 V asynchronous switching regulator. With embedded power MOSFET, it is designed to source up to 3 A DC current depending on the application conditions.
The 250 mV typical RSENSE voltage drop, the VBIAS pin embedded switch-over feature and the 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 also includes a 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 to reduce the total input RMS current.
