AL9901EV2 User Guide Universal High Voltage LED Driver with Integrated MOSFET General Description This demonstration board utilizes the AL9901 high voltage PWM LED Buck controller with integrated MOSFET providing a cost effective solution for offline high brightness LED applications. This user‐ friendly evaluation board provides users with quick connection to their different types LEDs string. The demonstration board can be modified to adjust the LED output current (140mA) and the number of series connected LEDs that are driven. Key Features Integrated 650V/2A MOSFET High output voltage, 50V ~ 86% efficiency <5% line regulation (100VAC to 240VAC) Universal AC input voltage (100VAC to 240VAC) No electrolytic capacitor Low BOM cost Applications A60 Type LED light bulb Other LED lighting AL9901 EV2 Specifications Parameter Value Input Voltage Output Power LED Current LED Voltage Efficiency Number of LEDs 100 to 240VAC 6 – 8W 140mA (Adjustable) 51V ~86% 17 LEDs in series (Under Tested) 0.6 ” x 2.4” x 0.6” Yes XYZ Dimension ROHS Compliance Evaluation Board ACLED+ AC+ Figure 1: Top View AC+ LEDLED+ AC- Figure 2: Bottom View Connection Instructions Input Voltage: 100 to 240VAC (AC+, AC‐) LED Outputs: LED+ (Red), LED‐ (Black) AL9901EV2 REV1 March 2015 www.diodes.com LED- Page 1 of 8 AL9901EV2 User Guide Universal High Voltage LED Driver with Integrated MOSFET Evaluation Board Schematic Figure 3: Evaluation Board Schematic Evaluation Board Layout Figure 4: PCB Board Layout Top View Figure 5: PCB Board Layout Bottom View Quick Start Guide 1. By default, the evaluation board is preset at 140mA LED Current by R5 and R6. Non‐ Dimmable by R2, remove R2 to allow PWM Dimming input. 2. Ensure that the AC source is switched OFF or disconnected. 3. Connect the AC line wires of power supply to “AC+ and AC‐” on the left side of the board. 4. Connect the anode wire of external LED string to LED+ output test point. 5. Connect the cathode wire of external LED string to LED‐ output test point. 6. Turn on the main switch. LED string should light up.
