Part Number: PMP9444 Other Parts Discussed in Thread: UCD90120 , LMZ31503 , TPS84320 I have a project driving a Xilinx Ultrascale FPGA, and my design is referencing PMP9444
1. I see that UCD90120 have a GPIO TRIM signal connect to LMZ31503 with serial resistor…
Part Number: LMZ31503 Other Parts Discussed in Thread: LMZ31506 Please let me know about internal inductor value for LMZ31503.
By the way, is LMZ31503 internal inductor value not same as LMZ31506?
Best regards,
Satoshi
Part Number: LMZ31503 In the datasheet, there's a note that indicates PWRGD "is in a defined state once VIN is greater than 1.0V" (page 24) . We're using PWRGD to monitor the status of the output voltage by connecting this signal to a pull-up resistor…
Part Number: LMZ31503 Per section 9.7 on sheet 18 of the datasheet, the recommended pull-up resistor value is between 10K and 100K to a voltage source that is 5.5V or less. We're trying to use the PWRGD signal to turn on a status LED and noticed that…
Part Number: LMZ31503 Other Parts Discussed in Thread: LMZ31506 , I have question about RRT: switching frequency setting resister for LMZ31503 and LMZ31506, please see below.
①The below thread is described RRT accuracy is ±20%, but high fsw condition collision…
Part Number: LMZ31503 Other Parts Discussed in Thread: LMZ31710 Hi team,
The maximum output voltage of the LMZ31503 is 5.5V.
Can I use it at 5.7V?
Or can the output voltage be increased in the same way as the SNVA749?
Best Regards,
Part Number: LMZ31503 Other Parts Discussed in Thread: TPS54320 Please let me know about two points below for LMZ31503's INH/UVLO pin function;
・About internal pullup, below thread is described " The INH/UVLO has an internal pull-up to Vin ".…
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…
