Preliminary
65V 1A mon Anode Capable LED Driver
With Internal Switch and Wide-Range Current Sense
General Description
The MY8103 is a mon anode capable step-down constant-current LED driver with internal MOSFET and wide-range current sense. The MY8103 provides a cost-effective design solution for architectural and ambient lighting, LED bulbs, and other LED applications.
The MY8103 operates from a +8V to +65V input voltage range and can provide an output current up to 1A. Output current of MY8103 is set by an external resistor connected between CSP and CSN pins. Dimming is controlled by an external control signal to the VDIM pin. The VDIM pin accepts either a DC voltage or a PWM signal, and applying a voltage of 0.4V or lower to the VDIM pin turns off the output current. The MY8103SE has two error outputs to indicate various fault conditions.
