Hello
I use IC(UCC27200D), input signal(pin5 and pin6) is connected to LM5037(pin13 and pin12), IC power is 12V, VDD capacitance is 1uF , HB to HS is connect 0.1uf ceramic capacitance, HO and LO is not connect anything. measurement LO is normal have pluse wave , but HO always keep 12V.
Why is HO keep 12V ?
Thanks
