EMD2081 - Constant Current LED Lighting Driver

General Description

The EMD2081 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.

ESMT EMD2081 Constant Current LED Lighting Driver With PWM Dimming Control General Description The EMD2081 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 EMD2081 switches at 1.2MHz and allows using small inductor and both of input/output capacitors. An internal compensation can reduce external component.
