Other Parts Discussed in Thread: LMZ22010, LMZ31520, LMZ30602, , LMZ31707
For a FPGA power supplies sequencing, I need to cascade these supplies:
LMZ22010 (POK) => | (INH) LMZ31520 (POK) |
| (INH) LMZ31704 (POK) | => | (INH) LMZ30602 (POK) |
| (INH) LMZ31704 (POK) | => | (INH) LMZ31707 (POK) |
| (INH) LMZ31704 (POK) |
My question is : Can I connect the INH signals of 2 DCDC converters together in order to control them with one PGOOD signal which is Open Collector ?
I need to connect the INH signals of these DCDCs together:
LMZ31520 & LMZ31704
LMZ30602 & LMZ31704
LMZ31707 & LMZ31704
For the LMZ30602, I read that I cannot connect an external pull up resistor to INH. If I connect the INH pin of the LMZ30602 to the one of the LMZ31704, will I have problem with the current source inside the LMZ31704 ?
