Other Parts Discussed in Thread: TPS51604
We've DIN TPS59641 in our customer, but we met some question with the schematic design. Could you please give some comments on the following questions?
1. Our customer do the design refer to the typical application Figure 56 in the datasheet. And the'd like to know the function of R9, which I high light in the figure below. Since the voltage of V5DRV is down below spec during test, they replace the 10ohm R9 with 2.2ohm resistor, wii this cause any problem?
2. They also use our FET driver TPS51604, please refer to the schematic below. Is it ok if we connect V5DRV to TPS51604 VDD pin? Could the pin connect to +V5SB?
