Hi
1. LM5119 is used in customer side, interleave buck, the output is 12V. so customer want that at start up, the internal VCC regulator is used, after 12V is stable, 12V is used to provide VCC power.
On LM5119 EVM, a diode from output to VCC is inserted. customer want to know how to set VCCDIS pin (pin 8)?
2. Diode Emulation Mode is not needed, so customer need to connect DEMB to VCC2. on EVM, this is a resistor R16, but this is no value shown.
do customer need this resistor or connect to VCC2 directly? if R16 is needed, what's the recommended value?
thanks.
