Other Parts Discussed in Thread: TIDA-050038
Hi,
We desighed a circuit consist of LP873347RHDT and TPS6521825RSLT for i.MX8M mini.
But PGOOD is fixed at Low.
BUCK0 and BUCK1 output is correct voltage.
So, I think there is a problem with LDO input or output.
Since LDO0 and LDO1 are not used, the connection is as follows.
VIN_LDO0 +5V(=VANA)
VIN_LDO1 +5V(=VANA)
VOUT_LDO0 NC
VOUT_LDO1 NC
Can you give me an idea of what is wrong with the circuit.
In drawing of TIDA-050038, VIN_LDO connected to the +3.3V. Is this a problem?
