Alfa-MOS AF1800A Technology 600V, 1A, 300KHZ PWM Universal High Brightness LED Driver General Description 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 programmed using a single resistor. The LED string is driven at constant current rather than constant voltage, thus providing constant light output and enhanced reliability. The output current can be programmed between a few milliamps and up to more than 1.0A. AF1800A uses a rugged high voltage junction isolated process that can withstand an input voltage surge of up to 600V.
