Hysteretic, Buck, High Brightness LED Driver w/ High-Side Current Sensing

The AT9919 is a PWM controller IC designed to drive high brightness LEDs using a buck topology. It operates from an input voltage of 4.5 to 40VDC and employs hysteretic controlwith a high-side current sense resistor to set the constant output current.The operating frequency range can be set by selec Hysteretic control with high-side current sensing \nWide input voltage range: 4.5 to 40V \n>90% Efficiency \nTypical ±5% LED current accuracy \nUp to 2.0MHz switching frequency \nAdjustable constant LED current \nAnalog or PWM control signal for PWM dimming \nOver-temper;
