AF1800A driver equivalent, universal high brightness led driver.
10V to 600V input range > 90% efficiency Constant current LED driver Applications from a few mA to more than 1.0A output LED string from one to hundreds of diodes PWM low.
from a few mA to more than 1.0A output LED string from one to hundreds of diodes PWM low frequency dimming via PWMD pin .
The AF1800A is a peak current PWM high efficiency HBLED driver control IC. It allows HBLEDs from voltage sources ranging from 10VDC up to 600VDC. The AF1800A controls an external MOSFET at fixed switching frequency up to 300kHz. The frequency can be .
