PAM2863 Datasheet (Power Analog Micoelectronics)

PAM2863, 2A LED Driver

The PAM2863 is a continuous mode inductive step-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 4.5V and 40V and provides an externally adjustable output curr
