GENERAL DESCRIPTION

The PA5711 is a High-Efficiency LED driver with multiple dimming options that include Pulse Width Modulation (PWM), Linear dimming (LD), Motion Detection (MD) and Light sense (LS) inputs. PA5711 features a direct gate driver control through an active high enable pin. It has an internal oscillator whose frequency can be set externally through a resistor.
