Hello All,
Currently working on a project, wherein have following specifications,
1 Vin - (for both the SMPS IC, From Vbatt - 12V to 40V )
2. Vout - from 1st Post regulator is from 0.8V to 40V
3 Iout upto 20A
4. Pre Regulator is a IC that outputs from -3V to -17V (inverting smps IC)
Here my dsPIC 30F4011 will digitally control the first IC as it has FB pin. The post regulator does not have a pin to adjust its output voltage.
Question is in any way is it possible to get a 0V output from either of the IC or any concept to have 0V as Vout by changing the ground or some method ???
Vout 1 will be from post reg from 0.8V to 40V
and
that from Vout 2 will be from -3V to -17V .
Attached the diagram
Thanks in advance
AB
