I'm using the TPS65070 as Power-Manager of an IIoT-System.
As power-supply I use LiPo or/and AC. After booting the TSP EN_DCDC1 is high and in the CON_CTRL1-Register there is the default setting “01111111”
This means after pulling down PB_IN the DCDC1-Converter should start when EN_DCDC1 is high. (While pulling down PB_IN, POWER_ON is set high)
The first time after attaching a power supply the TCP boots properly and the DCDC1 supplies the configured voltage.
After shutting down with pulling POWER_ON to low a reboot of the TPS doesn't start the DCDC1.
How can I fix this problem?
Yours sincerely,
