Hi Eileen,
Thank you for the information about the calculation method.
Can I use this result as the design value for LMZ31506?
Also, could you please include this information in the TI documentation to be used not only for this E2E but also for the design…
Part Number: LMZ31506 used two LMZ31506,frist LMZ31506 PWRGD pin could drive the second LMZ31506 INH/UVLO?
INH/UVLO pin could direct connect PWRGD pin?

Part Number: LMZ31506 The board was working fine, but at some point the LMZ31506RUQR's VOUT output (+3.3V) went to 0V.
・When I measured the resistance value between VOUT and GND after it became 0V, it was 1.9Ω. ・The resistance value between VOUT…
Part Number: LMZ31506 When LMZ31506 startup, power good output is delayed about 6ms.
Please refer below waveform;
※ch1: Vin (5V), ch2: Vout (1.03V), ch3: PWRGD
Is there any reason for PWRGD delay?
If there detailed schematic, please let me e-mail address…
Part Number: LMZ31506 We're using an LMZ31506RUQ to generate 1.0V from 5.0V - which it is doing - and then using the PWRGD output of that device to enable 2 LMZ31503RUQ's,1 LMZ31503RUQ, and 1 TPS7A8801RTJ. However, the outputs of these sequenced devices…
Part Number: LMZ31506 Hi there,
We are using LMZ31506RUQ in our design and we are trying to qualify this part against rated load of 6A. Buzzing or humming noise comes out of this module under following conditions;
1) When load current goes above ~5.4A …
Part Number: LMZ31506 Other Parts Discussed in Thread: LMZ31503 , TPS54320 Greetings, we are attempting to track a 1.8V turn on (LMZ31506) to a 3.3V turn on (LMZ31503). The resistors we've calculated are R1 = 37.8K and R2 = 18.9K. Unfortunately this results…
Part Number: LMZ31506 Other Parts Discussed in Thread: LMZ31710 , Can INH / UVLO pins be used with 0V / + 3.3V active controls (CPLDs, power sequencers, etc.) instead of open drains?
In this case, a pull-down resistor (about 1k to 10kΩ) is connected to…
Part Number: LMZ31506 Could you tell us about the PWRGD terminal specifications of the LMZ31506RUQR?
There is a description of the TYP value for the PWRGD threshold, but there is no description of the Max value and Min value.
Could you tell me about the…
