BD9207FPS集成电路（IC）的LED驱动器规格书PDF中文资料

BD9207FPS属于集成电路（IC）的LED驱动器。由罗姆半导体集团制造生产的BD9207FPSLED 驱动器器件属于 LED 驱动器电源管理集成电路 (PMIC) 系列，可通过标称固定电压的电源为负载（通常为发光二极管）提供电流，并且电流可控。它与用于电压调节的类似产品的主要区别在于，这类器件提供较低的反馈电压（以提高系统能效），而且通常可对器件工作点进行外部控制，可在照明应用中用于实现调光功能。

●Description

BD9207FPS is a LED driver with built-in step-down switching regulator and incorporates the built-in switching MOS EFT 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.

●Features

1) Maximum switching current of 1.5A

2) Built-in Pch switching MOS FET for high efficiency

3) Low loss because feedback voltage is as low as 0.2V

4) High oscillating frequency of 900KHz (Fixed)

5) Built-in soft start function

6) Built-in overcurrent protection circuit (OCP)

7) Built-in thermal shutdown circuit (TSD)

8) ON/OFF of output is possible by STBY terminal.

9) Compact surface-mount TO252S-5 package

●Applications

・For use in the light sources of PPC

・Printer etc. and the LCD backlights ofLED lighting apparatus & monitor

・Note PC etc.
