产品概述
描述
The STEVAL-ILL079V1 product evaluation board is based on LED6000 monolithic current source for high power LED driving. Thanks to the wide device input voltage range, alternative topologies like inverting buck-boost can be effectively implemented. Eight white LED (30 V max.) can be powered by 0.5 A programmed current. Digital dimming is implemented by driving the dedicated DIM pin and the necessary level shifting is achieved with inexpensive external circuitry. The LED6000 is a 61 V asynchronous switching regulator, with an embedded power MOSFET, designed to source up to 3 A DC current depending on the application conditions. The 250 mV typical RSENSE voltage drop, the embedded switch-over feature on the VBIAS pin and the light load management (pulse skipping) are intended to maximize power conversion efficiency across the entire load range.
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.
