AP8802 1A LED STEP-DOWN CONVERTER Description The AP8802 is a step-down DC/DC converter designed to drive LEDs with a constant current.
The device can drive up to thirteen LEDs, depending on the forward voltage of the LEDs, in series from a voltage source of 8V to 48V.
Series connection of the LEDs provides identical LED currents resulting in uniform brightness and eliminating the need for ballast resistors.
The AP8802 switches at frequencies up to 700kHz.
This allows the use of small size external components, hence minimizing the PCB area needed.
Maximum output current of AP8802 is set via an external resistor connected between the VIN and SET input pins.
Dimming is achieved by applying ei...
