Part Number:LM5050-1
Hi TI,
A user has a problem with the GATE output voltage level when driving a buck/boost circuit, needs assistance, and does not know who to contact at TI.
"I connected a DC power supply to the input of it and it turns on FET by creating a Vgs of 3.5V. Below are my voltages when I connect the output of buck regulator to LM5050
Pin4 – 15.6V
Pin5 – 15.9V
With the above condition, the body diode in the FET conducts and the voltage at pin 6 is 15.6V, but its heating to 90C. What would be inhibiting LM5050 form providing a Vgs to enhance the FET when I connect my output of buck regulator to it? "
