EV4001-S-00A 350mA, Universal-Input, WLED Driver with Passive PFC Evalvation Board DESCRIPTION FEATURES The EV4001-S-00A is an evaluation board for the MP4001. The MP4001 is a high-efficiency step-down converter designed to drive highbrightness light-emitting diodes (LEDs). The EV4001-S-00A can supply a maximum output current of 350mA to drive 10V-to-30V LED strings from an input voltage of 90VAC to 265VAC at 50Hz/60Hz. Applying a pulse width modulated square wave signal between the DIM and GND pins implements PWM dimming. The EV4001-S-00A meets EN55015 EMI standards. The EVB fits in PAR-22 lighting fixtures.

Connect the LED string between “LED_P” (anode of LED string) and “LED_N“ (cathode of LED string). 2. Connect the AC input voltage between “N” and “L” the AC input terminals as shown on the board. 3. Turn Power Supply off. 4. Preset AC Power Supply to 90V AC input 265V. 5. Turn Power Supply on after making connections. PWM Dimming The EV4001-S-00A can use PWM dimmed by applying a square TTL-compatible signal between DIM and GND terminals. Since there is no galvanic isolation on the board, care must be taken to prevent damage to the PWM dimming source. Suggested use of an opto-isolation to drive the DIM pin.
