Other Parts Discussed in Thread: LM5146-Q1
Datasheet page 8 VCC REGULATOR TYP 7.5V (MIN 7.3 and MAX 7.7V),
But I got Vcc voltage is 10V at no load and 10A load, what’s happen ?

Hi James,
The LM5146-Q1 EVM has a diode from Vout to VCC, hence the higher VCC voltage. This reduces bias power dissipation, particularly at high Vin.
