Hi Sir 

My customer currently use TPS61181 in 12~13.2Vin/ Vout 22V 20mA * 6 channels. 

But their new project concern about efficiency. they want to check if there have similar part(P2P is better). but efficiency is better solution?

    Hi Bogey,

         You can try with TPS61177A/TPS61187/LP8556 since it can change the switching frequency, it may help to achieve better efficiency. 

         Can you share us what's the detail application? What's the efficiency now? And what's the target efficiency?  We are planning to do a high-efficiency backlight driver. 

    Regards

    Sean
