Hi TI,
I used the part TPS7A6650H-Q1 in my design now, when the power is on, I test the Vout is 5V in the beginning ,it is normal. but a few seconds later i found the input current get larger to 50mA rapidly, and the TPS7A6650 get heater, and Vin have some sparks. it seems the part is not stable. how could i debug, thanks
Briefly describe the circuit as below:
Vin :12V
input capacitor: 1uF
output capacitor: 3uF
PG: connect 10K resistor with Vout
CT: connect 1nF to GND
EN: connect with Vin directly.
