High current DC to DC converters - non isolating

[engr_joni_ee]

Hi,

I am looking for the following non-isolated DC to DC converters for commercial application. I have searched but not able to find the components. I need some help in finding these components. Any help will be appreciated.

1- 1.0 V ~ 4 A
2- 1.8 V ~ 2 A
3- 1.35 V ~ 1.2 A
4- 0.675 V ~ 1.2 A

Go to digikey.com, for example, and enter your parameters. There are plenty of options.

These low voltages are mostly the province
of POL DC-DC chips, lash up your own passives.

Your 0.675V application narrows the field a lot,
you'd need a chip with <= 0.6V reference (many
are 0.8V and higher, designed back when 1.0V
was lower than anyone needed).

I have searched and I don't find many options because of high current requirement.
