EMD2080 - Constant Current LED Lighting Driver

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.

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. g g g g g g Features g g Supply Voltage: 6V ~ 30V Driving Current: n Up to 500mA @VIN=12V, VOUT=22.4V Over Voltage Protection: 36V Shutdown Current < 1μA Reference Voltage 0.245V Internal Soft Start and Compensation 1.
