MA2201 - Step-up LED Driving Controller
The MA2201 is a current mode step-up LED Driving controller.
The input voltage range is widely from 3.5V to 28V, designed to drive an external N-channel MOSFET.
Output LED current is programmable with VFB = 0.2V.
The PWM switching frequency is 600KHz and allows usage of small external inductor.
