ROHM, BD9207FPS-E2Step-Down Switching Regulator, 1-Channel 1.5A Adjustable 5 + Tab-Pin, TO-252S

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.

Maximum switching current of 1.5A
Built-in Pch switching MOS FET for high efficiency
Low loss because feedback voltage is as low as 0.2V
High oscillating frequency of 900KHz (Fixed)
Built-in soft start function
Built-in over current protection circuit (OCP)
Built-in thermal shutdown circuit (TSD)
ON/OFF of output is possible by STBY terminal.
