Datasheet Summary
LED DRIVER PR4101
High Power LED Buck Driver PR4101
The PR4101 is a LED buck driver for driving one or several high power LEDs in series. The supply voltage can be up to 40V, with an output current of more than 1A using an external N-channel MOSFET switching transistor. The PR4101A with additional PWM and power down input is delivered SOP14 packaged, while the PR4101B is offered SO8 packaged.
