RT4722,PDF数据表下载

RT4722 pdf资料下载The RT4722 is a triple channels DC-DC converter which is designed to provide the power of AMOLED. It integrates step up DC-DC and an inverting converter to provide the positive and negative output voltage required by AMOLED. For the portable application, board space and efficiency are always major concerns. The high switching frequency of the RT4722 allows the use of low inductance inductor to save the board space. For the negative and AVDD output voltage, both can be programmed by external MCU through single wire (SWIRE pin). The output voltage range of negative output voltage is 1.4V to 5.4V and AVDD voltage is 5.8V to 7.9V. The RT4722 has OTP, SCP, UVLO and over current protections. The RT4722 is available in a WQFN-16L 3x3 package to achieve saving PCB space.Datasheet pdf资料数据表下载
