Part Number: LM27762 Dear Sir,
we are using lm27762 for generating +/- 4V but our negative voltage is not working. positive voltage is working fine and the input of lm27762 is 5V
please give solution
Regards
Mani
Part Number: LM27762 We are noticing negative output voltages that are out of spec for a LM27762 designed to output +/- 5 V. The device receives 4.9V (measured). I measure FB- as -1.123 V, which is not what the data sheet specifies, 1.22. Our output voltage…
Part Number: LM27762 Hello, LM27762 datasheet 8.2.2..4 says “The LM27762 only requires the use of a 2.2-μF ceramic output capacitor for stable operation. For typical applications, a 2.2-μF ceramic output capacitor located close to the output is sufficient…
Part Number: LM27762 Other Parts Discussed in Thread: LM2776 Links within LM2776 datasheet to Webench Power Designer do not work. I was hoping to look at the design for 5.5v Vin to +/- 5V ~200mA, please advise.
Hi Alassane,
These waveforms are not sufficient to help with the debugging. The time-division is at 20ms whereas the LM27762 operates typically at 2MHz, so with this time scale it is impossible to see what happens during the switching times. Since this…
Part Number: LM27762 Hi Team, Our customer is looking for the temperature coefficient values for the output voltages of the LM27762, There's no graph for the Vout vs. operating temperature in the datasheet to provide this information to the customer.…
Part Number: LM27762 hello everyone,
i was trying to make some testing on LM27762 before i use it in other projects.
so i made a pcb with Altium and designed the schematic based on the values from Texas Instruments site using WEBENCH so the voltage…

Dear Madam, Sir,
I intend to use LM27762 in order to obtain +2.5 V and -2.5 V from a 5 V supply, to feed precision operational amplifiers such as the OPA365.
I downloaded…
Part Number: LM27762 Hi Experts,
Good day. Seeking help on this query:
See below circuit, built to get +5/-5V output. The resistor values in squares are from the evaluation board.
Not sure of the Pgood resistor has to be connected for a correct…
