Description
- Application Circuit for L6902D driving up to 6 high current white LEDs. The L6902D is a simple and complete step down switching regulator, with adjustable current limit. This device is a good solution for LEDs lighting applications, thanks to its inner current loop that allows regulating a constant current at the output with a minimum voltage drop across the external sense resistor (100mV)
