EMD2081-Constant Current LED Lighting Driver


EMD2081-Constant Current LED Lighting Driver With PWM Dimming Control DataSheet

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.
    The EMD2081 include current limit, over voltage and
thermal shutdown protection. The EMD2081 is
available in MSOP-10 package.

Features
 Supply Voltage: 5.2V ~ 30V
 Driving Current:
 Up to 500mA @VIN=12V, VOUT=23V
