Hii

I have a requirment of negative supply voltage generating from input -15V to output -6V or -7.5V,1.5A or 2A for one of my application. I cannot use LDO since losses will be high can u suggest any switcher IC for the same.

Hi Sneha,

You need a boost regulator for -15V to -6V conversion.

I will forward your inquiry to other production line.

Dear Sir,

Please refer to SLVA985 and PMP9624 for a referecne. For the SLVA985, you just need to change TPS61088-Q to TPS61175 or TPS61178.
