NPA Number 001 New Product Announcement AP8803 Cost effective 3W LED driver for consumer applications Description The AP8803 is 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 off the h LEDs, LED iin series i ffrom 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 coupled with it requiring only 4 external components produces a small solution footprint. The accuracy, temperature range and cost make it ideally suited to cost sensitive domestic lighting application. The Diodes advantage The AP3154A and AP3156 provide a simple cost effective solution for small screen LCD backlighting Small footprint TSOT23-5 High power density Drives multiple 3W LED Cost sensitive solution to MR16 lamps PWM and DC dimming Versatile dimming; DC for thermal control, PWM for brightness control It is available in green mold compound as standard High switching frequency up to 700kHz Small inductance value and size Green mold compound (No Br, Sb) and Pb-free RoHS compliant finish Better for environment; no mercury unlike CFL.
