Tool/software:
Hi Team,
I am using the PMIC part TPS65262-2RHBT in my design. I need to sequence the outputs of this PMIC. LDO1 output should enable Buck 1 and Buck1 output should enable Buck 2. I have connected a 100k Ohm pull-down
resistor and a 0 Ohm pull-up resistor to the enable pins of buck 1 and buck 2. The pull-up voltages will be the outputs of LDO 1 and Buck 1. The 100k pull-down resistor will make the enable pins low, when the LDO 1 and
Buck 1 outputs are not generated and avoids any unstable states on the enable pin. Once the LDO 1 and Buck 1 outputs are generated, the current will flow to the enable pins of LDO 1 and Buck 1 via the 0 Ohm pull-up
resistor (Current will avoid the high resistance path of with 100k pull-down resistor).
Please provide feedback on this enabling concept.
