A703 is a high voltage, adjustable constant current
driver for LED applications. Two regulated current ports are
designed to provide uniform and pure DC constant current
sinks for driving LEDs within a large range VF variations.
A703 provides users 2-channel constant current ports
to match LEDs with equal current. Users may adjust the
output current from 20mA to 150mA through an external
resistor, RSET, which gives users flexibility in controlling the
light intensity of LEDs. It also could adjust LED brightness
from 0% to 100% via enable pin (EN) with Pulse Width
Modulation signal.
The thermal protection function protects IC from over
temperature (150°C). Also, the thermal pad enhances the package power dissipation.
