Part Number: LM27761 Tool/software: I would like to use LM27761 to generate -1.3V from +5V.
The part's spec shows the minimum Vout as -1.5V. In the same time, the Vref is 1.22V. Logically, it should be capable to produce -1.3V.
I did the test and…
Part Number: LM27761 Tool/software: I want to use LM27761 to convert from+5V to -4.8V. The output waveform (TP15) shows that the output voltage drops by about half after power on, and the temperature of the thermal imaging display chip rises rapidly.…
Part Number: LM27761 Tool/software: Dear Texas Instruments Support Team,
I hope this message finds you well.
We are currently working with the LM27761 Low-Noise Regulated Switched-Capacitor Voltage Inverter in our project, aiming to achieve a -2.2V…
Part Number: LM27761 Hi team,
We are evaluating the LM27761 under the following conditions:
Vin = 5V (generated on board, current capacity: 3A) Vout design target = typ. -5.05V (R1 = 160kohm ±1%, R2 = 51kohm ±1%) Iout = 6mA
However, we measured…
Part Number: LM27761 Tool/software: I could not get PSPICE transient simulation for LM27761 to converge. I was trying for -2.5V supply. What could be the issue?

Part Number: LM27761 Tool/software: Subject: Seeking an LDO to Generate -0.7V @ -1.39mA and -0.7V @ -1.5mA
I am looking for an LDO that can generate a negative voltage of -0.7V at currents of -1.39mA and -1.5mA. After searching through various options…
Part Number: LM27761 Tool/software: Hi,
My design using the LM27761 is sometimes not working as expected: under certain circumstances it provides an unstable negative output voltage that is way too low. It is designed to generate -2.7V from a 3.2V…
Part Number: LM27761 Tool/software: Hi, I am new to the forum and am unable to get the LM27761 to work properly. R1 is 120K ohms, R2 is 100K ohms. I am using surface mount capacitors per the below schematic. They are all in the 0603 package and a combination…
