Other Parts Discussed in Thread: TPS62113, LM5155, TPS61170

I'm selecting power regulators for my design. Now I'm checking for switching regulator with
1. -6V @ at least 1A output from 5V input
2. 30V @ at least 1A output from 5V input

Hi Nidhi,

a possible to negative voltage requires a buck converter. please find the buck converter with >12V input and >1A output.such as
TPS62113

the 30V output should be a boost controller, such as LM5155

Hello

Thank you so much for your support.

I've changed my architecture in such a way that, I need around 10mA current output from both 30V and -6V regulators. Recommended is charged pump regulator. Suggest the best option for the same.

Hi Nidhi,

the 30V output should be a boost such as TPS61170, as charge pump can't support this high voltage.

the -6V could be charge pump, but the typical output would be -5V if the input is 5V.
