Part Number: LMZ31520 Other Parts Discussed in Thread: LMZ31530 Hallo,experts,
In the LMZ31520 data sheet page 4 note (3), it is recommended to use a very low-leakage transistor to drive the INH pin (I<300nA).
Is it possible to relax the above leak…
Part Number: LMZ31520 The PCB Board having LMZ31520 IC was kept for burnin of 192 hours.The IC was functioning properly till the end, but suddenly failed(non output). Please find the attached waveforms captured at the PH Pin of the LMZ31520 IC. Graph1…
Part Number: LMZ31520 Hi Team,
My customer is evaluating LMZ31520 on their board now. They would like to know impedance between VOUT pin and PGND pin of LMZ31520 under Power-Off state and also impedance between SENSE+ pin and AGND pin , for inspection…

Hi,
LMZ31520RLGT is used in one of our project for generating the 1.5V supply . When powered ON the board, This IC is not giving the output . In further analysis we found INH pin is low. This INH pin driven by CPLD through one MOSFET…
Part Number: LMZ31520 Hi,
SENSE+ seems connected to ADJ pin via 1K43 internally.
For my application, the resistor between ADJ pin and VOUT must be >=6K
Can I add extra resistor (e.g. 4K7) in series from SENSE+ to Vout to achieve this without unexpected…
Part Number: LMZ31520 Hello,
The 72 pins B4QFN Package Drawing document (R-PB4QFN-N72) does not contain Land pattern example, Solder mask detail, Land pattern example via detail and Solder Paste example as in the 59 pins B4QFN Package Drawing document…
Part Number: LMZ31520 Hello,
I want 2.5V~3.5V @ 12A with Adjusting Voltage power.
AGND pin description of LMZ31520 is 'Do not connect AGND to PGND'.
But snva709 Document is AGND pin connected GND.
What should I do?
I refer to this :
Best Regards…
Part Number: LMZ31520 Other Parts Discussed in Thread: LM10011 Hi Team,
My customer is designing a new project. We just penetrate our LMZ31520 to customers, but several questions need team's quick support to confirm:
1. Is the V5V pin(pin 61) output…
Part Number: LMZ31520 Hi,
I have a board designed with the LMZ31520 to provide the 1.0V rail for the LAN phys:
vin=12V,
Vout=1.0V @ 14A max
Please refer to figure 1 in the attachment for the schematic.
When I heat the LMZ31520 with a heat gun to a temperature…
