Part Number: LM27762 Other Parts Discussed in Thread: OPA928 Tool/software: I am working on requires powering an op amp (OPA928) via dual +/- 3V DC supply with low noise. I am constraint to a single power supply channel. This is my first time trying…
Part Number: LM27762 Tool/software: My name is Oda. I purchased your LM27762 evaluation board and confirmed the behavior of PGOOD under negative voltage factor. According to P10 of the datasheet, it is stated that the PGOOD goes to “H” level when it reaches…
Part Number: LM27762 Other Parts Discussed in Thread: TPS65131-Q1 Tool/software: Hi TIer
My customer need a charge pump with a +-6V output and a current greater and at least 150mA output as LCD power supply , do you have a recommendation?
I see LM27762…
Part Number: LM27762 Tool/software: Hello,
I'm using the LM27762 to provide +/- 2.75V for precision analog circuitry. I'm trying to decide if the downstream analog ICs' decoupling caps should be differential (between +/-2.75V) or common-mode (each rail…
Part Number: LM27762 Tool/software: Hi,
I am trying to evaluate LM27762 design to generate +/- 5V from 5.2V input voltage.
I have observed that voltage at VFB- pin is out of spec.
Please find following design values
Vin = 5.2
For +ive voltage
VFB+ =…
Part Number: LM27762 Tool/software: I would like to know about the setting range of the positive supply voltage. Is it possible to set it to be typ5V? (Is it possible to set it so that it could be 5.1V at max due to variations in resistors, etc.?)
Part Number: LM27762 Other Parts Discussed in Thread: ADS1120 Tool/software: I'm designing a PCB to power a sensitive analog sensor and read a differential analog signal (+/-10 mV) from the sensor. The input power to the PCB will be a noisy 5V, so I…
Part Number: LM27762 Tool/software: Dear e2e Support,
Do we have similar graph than the datasheet figure 5 to 8, with an input voltage of 2.7V and 3V? and ideally for a +/-5Vout.
Regards,
Part Number: LM27762 Hi,
We are planing to use this particular LDO in our project. I went through this thread where someone faced problems while using LM27762 , is this issue been solved? or is there any alternates that can be used for this?
Regards, …
Part Number: LM27762 Hi,
I'm trying to understand the operation of the PGOOD pin on this device but I find the working of it confusing.
Within the Pin Functions it says that Logic 0 = Power good, Logic 1 = power not good. I assume that this means…
