LED5000 - Wide brightness control and high design flexibility
The LED5000 is a monolithic buck switching regulator specifically designed to drive long LED strings with an input voltage range from 5.5 to 48 V, an output current up to 3 A and a very low feedback voltage (200 mV).
It embeds high-performance PWM circuitry for LED brightness. The highest design flexibility is given by the possibility to implement other topologies such as buck-boost (positive or negative) or floating boost
