Part Number: LM27762 Hi team,
The Vin pin appears to have a current limit of 500mA, but when the device was actually operated, the inrush current was not limited at 500mA. Is there a time delay before the limit is applied? Also, how much inrush current…
Part Number: LM27762 The spec for the part requires that the resistor to gnd on the negative feedback > 50k. I tried using a feedback to gnd resistor of 10k and it worked and the noise floor improved by almost 3dB. Is the 10k OK? Should I add a capacitor…
Part Number: LM27762 Part works after considerable effort but the part raises the noise level in the design in the 100kHz range. Where is this noise coming from and how can we reduce the noise?

Hello,
I am running into some problems with the LM27762.
I've configured it as a ±5V regulator, which is mainly used to generate bias voltages for cheap.
Above are the schematics. After discovering problems, I've entirely…

Kindly review this schematics and provide comments for the above. Required outputs are 5V and -3v3
When tried to simulate…
Part Number: LM27762 Other Parts Discussed in Thread: PSPICE-FOR-TI My goal is to generate +3V and -3V using this component. However when EN- is high (negative voltage active), the simulation fails and errors out after a bit. PGOOD is also high when it…
Part Number: LM27762 Hi Team,
LM27762 can output positive and negative voltage. I want to make sure that positive voltage and negative voltage both can output 250mA current at the same time?
Part Number: LM27762 Could someone from the application engineering team please contact me privately? This matter is very urgent and I will not make this inquiry public. Thank you so much.
Part Number: LM27762 Hello everyone, I need to develop a symmetric source of +-5vdc, to feed 4 load cells, the excitation of the load cells must be 10vdc (+5v/ -5v). the load cell is formed by 4 strain gauges of 300Ohms, the cell signal is 2mV/V. I would…
Part Number: LM27762 Other Parts Discussed in Thread: OPA355 , OPA863A The circuit i have is the same as the one in the datasheet, although I added more capacitance than what is listed. For some unknown reason, the negative output of this chip is positive…
