Overview
ESMT/EMP Preliminary EMD2080 Constant Current LED Lighting Driver With PWM Dimming Control General Description The EMD2080 was designed with high efficiency step up DC/DC converter with constant current source for driving lighting LEDs.
Wide input voltage range makes the application more flexible.
LED dimming can be achieved with pulse width modulation dimming on DIM pin.
The EMD2080 switches at 1.
2MHz and allows using small inductor and both of input/output capacitors.
An internal compensation can reduce external component.
