1 / 10 page  AP1694AEV11 User Guide 230VAC Triac Dimmable GU10 LED Driver AP1694AEV11 Rev2 Page 1 of 10 July 2015 www.diodes.com General Description This AP1694A Triac Dimmable GU10 12V/400mA Buck LEDs driver EV board use tapped transformer to increasing power conversion turn on duty cycle, boost current back to LED during ratio of tapped winding. Also the bigger gauge wire can be used as well as the large inductance can be suitable in switching loop which can reduce the switching current and the lower forward drop so that SBR diode can be used which can reduce the power consumption on the diodes. Key Features Typical 3% to 95% Dimming performance (Depends on dimmers brands) Boundary conductive switching mode Simple adjustable Constant Current Inductor Short Protection Low BOM cost PFC >0.9 & low THD. 200 ~265V AC input range >77% Efficiency With open, short, and wrong polarity LED protection Applications GU10 LED Offline small size bulb Candle size LED lamp Desktop lamps Under the counter lamps AP1694A EV11 Specifications Parameter Value Input Voltage 200 to 265VAC PFC > 0.9 LED Current 400mA (Adjustable) LED Voltage 12V Efficiency >77% Number of LEDs 4 LEDs in series (Under Tested) XYZ Dimension 28.5 x 16.5 x 14.5mm ROHS Compliance Yes Evaluation Board Figure 1: Top View Figure 2: Bottom View Connection Instructions Input Voltage: 230VAC (AC+, AC‐) LED Outputs: LED+ (Red), LED‐ (Black) |
