Part Number: BQ25570
Hello my question is
I set the voltage output is set to 3.3V.My system is a BQ25570 powering a system(MCU) at 3.3V. The system is on the regulated VOUT net of the BQ25570 (on the buck step-down).
But sometimes the built-in Lbuck of bq225570 will have a voltage below 1V.
Sometimes using the meter to measure the voltage and return to normal 3.3V
The following is my circuit diagram TPS62737 is not on the piece
