Description
The EV4005DN-00A is an evaluation board forthe MP4005/4005-A. The EV4005DS-00A is ahigh efficiency step-down converter designedfor driving high brightness Light Emitting Diodes(LEDs).The MP4005/4005-A integrates a 190VMOSFET in the floating buck converterstructure. EV4005DS-00A can supply amaximum output current of 350mA to drive 10to 30V LED strings from a wide input voltage 85to 110VAC with 50/60Hz.PWM dimming can be achieved by applying apulse width modulated square wave signalbetween the DIM and GND pins.The EV4005DN is meet CISPR-15 compliant.
