Part Number: TPS54540 Tool/software: Hi, For the IC TPS54540DDAR can we supply more than 8.4V to the ENABLE PIN to set " Under Voltage Lockout"? if so what is the maximum voltage we can supply.
in datasheet it is mentioned that when we exceed more than…
Part Number: TPS54540 Tool/software: attach the schematic. the issue is:
when the load is less than 0.7A, the Vout is working normally.
when the load is higher above 0.7A, the Vin will be pulled down to 4V, lead Vout can not output normally.
…

Part Number: TPS54540 Hi All
I did calculations for each component selection for TPS54540, but I didn't find the formula for Minimum Capacitor Input (CIN_Min)
I would like to know is there any equation for CIN_Min selection?
Looking forward…
Part Number: TPS54540 Hi All,
I tried to measure the switching frequency for IC TPS54540 , we get the normal frequency at 2MHz in the operating condition
But when I try to measure the start up sequence of Switching frequency with the Oscilloscope…
Part Number: TPS54540 Hi team:
my customer feedback that they uses the TPS54540 DCDC power supply chip, and uses the BUCK-BOOST method to output a negative 12V voltage. At present, there is one device in the production process, the output is only about…
