1 / 8 page ![]() Issue 2 – May 2012 © Diodes Incorporated 2011 www.diodes.com 1 of 8 AL8807EV4 USER GUIDE Performance • 12VDC and 12VAC input • 1.1A LED current • Drives 1 to 3 LEDs in series • 2% current regulation 9V to 30VDC (with 2 LEDs) • Ambient temperature range -40°C to +105°C Ordering Information Order Number AL8807EV4 Introduction This evaluation circuit demonstrates the AL8807 High Efficiency 30V 1.5A Buck LED Driver operating in a circuit providing 1.1A LED current in MR16 form intended to drive 1 to 3 high brightness LEDs in series with a total load voltage drop up to 10V. The circuit includes a 470µF reservoir capacitor to prevent flicker for 50Hz or 60Hz AC input power. EMC filtering is included to meet international standards including the radiated emission requirements of EN55015 and EN55022 Class B. The switching frequency is approximately 440kHz when driving 2 Osram Dragon Diamond LEDs. The construction uses a double-sided FR4 printed circuit board, 17 x 20 x 0.8 mm with 2oz/sq ft copper (70µm). Components are mounted on both sides. |
