The ACE703 is a PFM step-up DC-DC converter specifically designed to drive white LEDs with a constant current.

It can deliver stable constant output current from 0mA to 500mA by adjusting the external resistor.

Low start-up voltage (when the output current is 1mA)--------------------------0.8V The converter can output constant voltage from 2.5V to 6.0V or it can output constant current from 0 to 500mA by adjusting the external resistor. Output current accuracy -----------±10％ Low temperature-drift coefficient of the output current------------------±100ppm/℃ Only four external components are necessary: an inducto.
