Diodes’ cost effective 3W LED driver for lighting applications

Diodes Incorporated has launched the AP8803, a step-down DC/DC converter designed to drive LEDs with a constant current. The device can drive up to 7 LEDs, depending on the forward voltage of the LEDs, in series from a voltage source of 8V to 30V.

Series connection of the LEDs provides identical LED currents resulting in uniform brightness and eliminating the need for ballast resistors.

The AP8803 switches at frequency up to 700kHz. This allows the use of small size external components. The TSOT23-5 package and need for only 4 external components produces a small solution footprint.

The accuracy, temperature range and cost make it ideally suited to cost sensitive domestic lighting applications.

It is available in green moulded compound as standard.
