1A LED STEP-DOWN CONVERTER
Description
Pin Assignments
The AP8802 is a step-down DC/DC converter designed to drive
LEDs with a constant current. The device can drive up to thirteen

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
