Product details

Description

White LED PFM Step-Up DC-DC Converter 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.The ACE703 can drive one or more LEDs in parallel connection, also it can drive two in series, several in parallel connection from one or two battery cells.With overvoltage limit protection circuit interiorly, the chip and the external circuits wil

Features

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.
