Hi Sam,
Thanks for your feedback.
There are always multiple interpretations about same thing and usually history related to decision call this memory as OTP but in reality it means it is already programmed during manufacturing.
Reason why we don…
Hi Sreehari,
Field recently moved to a different role in the company. I am not sure how he was intending to measure this timing for you since the EVM has different capacitance values. I think it may be better to use the transient simulation models here…
Hello James,
The closed matching in our product line is LP8733-Q1. It is a smaller version with 2 BUCKs and 2 LDOs. So you can promote 2 x LP8733-Q1 for replacing MPQ7920.
Regards
Part Number: AM5706 Other Parts Discussed in Thread: LP8764-Q1 , DRA821 , TPS6594-Q1 , LP8732-Q1 , LP8733-Q1 , Hi,
According to the Jacinto7 DRA821 Evaluation Module (EVM) User’s Guide, there are MASTER PMIC (TPS6594-Q1) and SLAVE PMIC (LP8764-Q1).…
Part Number: TDA2EG-17 Other Parts Discussed in Thread: LP8732-Q1 , LP8733-Q1 Dear Team,
Our customer have some question as below,
In theory, it should start at the same time, but there is a 1.5ms start difference, according to (LP8733-Q1 and LP8732…
Hi Ranjith,
It seems like the input voltage is collapsing. 5V is used for the PGOOD/EN and it seems to start to shifting down. Same behavior is seen in 3.3V output voltage and the output voltage is shifting down due to the minimum voltage difference…
Hello,
Have you had any success resolving this issue? How are you configuring the LP8733-Q1 registers for your application? Please note BUCK0_CTRL_1 and bit 4 which forces the multiphase operation.
Can you confirm that when R3 is open and R2 is shorted…
Shlomi,
There are a couple different options you have here. The first would be to use the LP87332B-Q1, but keep the enable pin low, until you are able to modify the LDO0 output voltage through I2C. The second option would be to use the LP8733-Q1, which…
Jeff,
You are correct - the power sequence is part of the OTP program and cannot be modified. Our released OTP programs are described in our user guides (the power sequence is at the end):

Hugo,
The best option we have for I.MX8 is our customer configurable versions of the LP8733-Q1 and LP8732-Q1. These devices are I2C configurable so all of the voltages, sequencing, and other settings can be configured when the device is powered on…
