General Description

The AL9901, high-voltage PWM LED driver provides an efficient solution for offline, high-brightness LED lamps for rectified line voltages ranging from 85VAC up to 305VAC.

The AL9901 has an internal MOSFET that allows switching frequencies up to 300kHz, with the switching frequency determined by an external single resistor.

The AL9901 topology creates a constant current through the LEDs providing constant light output.
