LED LIGHTING DRIVER
1A LED DRIVER WITH 40VNDMOS INTERNAL SWITCH
DESCRIPTION
FEATURES
The A8180A is a continuous mode inductive step- Simple low parts count
down converter, designed for driving single or
multiple series connected LEDs efficiently from a
voltage source higher than the LED voltage. The device operates from an input supply between 6V
and 36V and provides an externally adjustable output current of up to 1A. Depending upon supply voltage and external components, this can provide up to 30 watts of output power. The A8180A includes the output switch and a high-side output current
sensing circuit, which uses an external resistor to set
the nominal average output current.
