1.5A Buck Converter LED Lighting Driver - BD9207FPS
BD9207FPS is a LED driver with built-in step-down switching regulator and incorporates the built-in switching MOS FET of Pch. Feedback voltage is as low as 0.2V and can suppress the loss on the sense resistance of LED. It is operated by PWM method with an oscillating frequency of 900 KHz and can use smaller coil than a switching regulator of low-frequency operation.
