AP880X Series Step-Down DC/DC Converter

Diodes' AP880X series a family of LED driver ICs significantly reduce the number and size of external components required by drive circuits

Image of Diodes Incorporated's AP880X Series Step-Down DC/DC ConverterOperating at switching frequencies up to 600 kHz, Diodes' AP880X series step-down, DC/DC converters require only four smaller and lower cost inductors and/or capacitors. Ensuring uniform LED brightness and eliminating the need for ballast resistors, the drivers suit a broad range of high-brightness, general illumination duties, including signage, architectural and emergency lighting, and MR16 lamp replacement.

AP880X ICs drive up to 13 series-connected LEDs with a constant current from voltage sources between 8 V and 48 V with efficiencies up to 92%. An integrated soft-start function reduces LED stress and extends lifetime. A choice between PWM and DC input dimming control increases design flexibility. All AP880X devices come in the industry standard SOP-8L package. The AP8800 and AP8801 are also available in the MSOP-8L package and the AP8802 in exposed pad DFN and SOP-8L packages.

AP8800

The AP8800 is a step-down DC/DC converter designed to drive LEDs with a constant current. The device can drive up to seven LEDs, depending on the forward voltage of the LEDs, in series from a voltage source of 8 V to 28 V. Series connection of the LEDs provides identical LED currents resulting in uniform brightness and eliminates the need for ballast resistors. The AP8800 switches at frequency up to 0.6 MHz.
