Part Number: LP8764-Q1 hello I have a question about the P876411A5RQKRQ1 used for the J721S2 PDN. I am trying to tie Buck 1,2,3,4 together and use them as High-Current. Is the voltage fixed at 0.8V? Or do I need to program it?
I understand that P876411A5RQKRQ1…
Part Number: LP8764-Q1LP8764-Q1: what are the differences between B4 and B5 parts (LP876411B4RQKRQ1 and LP876411B5RQKRQ1) apart from the I2C addresses being 0x4C and 0x58 respectively and say any factory OTP values for pre-programmed settings as per…

As slvaf93a - Scalable PMIC NVM Update Guide mentioned, if the data value of Page 0 register 0x82, ENABLE_DRV_STAT, is not 0x08, then the register CRC for Page 0 and Page 4 must…
Part Number: LP8764-Q1 Hello,
Is there a GUI or some other tool that would allow the user to configure the buck settings as needed, then spit out a bunch of register operations that can be used to program the buck regulators via I2C for the desired configuration…
Part Number: LP8764-Q1 I am designing a new PCB with a number of different rails:
I need to use the LP8764 in 3 different configs:
Quad phase (1 output) :20A
3 phase, 1 phase 15A, 5A
2phase, 2 phase 10A, 10A
Regarging the orderable parts, which is the…

Customer system is TPS65941213+LP8764+TDA4.
They report 3pcs high temp shutdown issue among 15Ku manufacture boards.
At 85C air temp, TPS65941213-Q1 and LP8764-Q1 Tj is around…
Part Number: LP8764-Q1 I am trying to program the NVM of the above part. The chip is connected using I2C to an ARM chip. I have wrote a program that uses the BIN file from the GUI and writes the registers in the sequence that is defined in slvaf93a. I…
Part Number: LP8764-Q1 Other Parts Discussed in Thread: LP87644Q1EVM I have a custom PCB that uses an LP876441B1RQKRQ1 and PIC to control it via I2C. The code has been tested with the LP87644Q1EVM and a PIC dev kit and there wasn't an issue enabling and…
Part Number: LP8764-Q1 We have a LP8764-Q1 based design. The GPIO4 is used as an enable input and there is no pull up selected for this input.
VCCA,PVIN_B1,PVIN_B2,PVIB_B3,PVIN_B4 = 5.0V
VIO = 3,.3V
We read VOUT_LDO = 1.8V
The actual design has 100K pullup…
Part Number: LP8764-Q1 Hi TI team,
I would like to check with you for the L inductance value buck 3 of LP8764-Q1.
You guys have recommended me typical value of 470pF, but could it be lower for 330nH?
As schematic figure below, I am going to change…
