Other Parts Discussed in Thread: UCC27200
I am using LMG1210 to drive EPC2045 in a converter similar to buck. The internal LDO was bypassed and 5V is provided by a bench power supply. BAS170W was used as the bootstrap diode. The switching frequency is 3 MHz.
I ran the prototype and noticed the HO voltage is smaller than LO voltage by ~ 1V. Was it caused by the forward voltage drop of bootsrap diode? Is there anything else I could change to reduce this voltage drop?
Thanks
