Part Number: LM27762 Hello,
I have two boards using the same schematic. One board correctly generates +2.7 V and -2.7 V, while the other one fails to generate the -2.7 V rail.
Below is the layout of the board that does not work correctly:
Interestingly…
Part Number: LM27762 Hi,
I am using LM27762 to generate +/-5V from 5.35V Supply.
The issue I am facing is there is a small saw-toothlike noise on the negative supply which is affecting our sensitive elctronics.
I attached the schematic - the output…
Part Number: LM27762 Hi Teams,
Can this charge pump achieve outputs of+4.5V and -4.5V. At present, the input power supply is 5V, and the output terminals R1, R2, R4, and R3 are 274K, 100K, 100K, and 270K, respectively. Is this reasonable?
This 5V…
Part Number: LM27762 Hi Team

Tool/software:
I'm using the LM27762 to step 5V down to +3.3V and -3.3V on a PCB. For my application I'm using <50mA of current draw from each channel. I've had issues getting this chip to work properly, and made a separate small…
Part Number: LM27762 Other Parts Discussed in Thread: INA851 , Tool/software: Hello Support Team
I plan to use an LM27762 for the bipolar power supply of the INA851 instrumental amplifier in my design. However, due to the low load current, the LM27762…
Part Number: LM27762 Other Parts Discussed in Thread: LM27761 I am using this charge pump only to generate a negative output rail, I do not want to use the positive output feature. The datasheet indicates that OUT+ and FB+ SHOULD NOT be left floating…
Part Number: LM27762 Tool/software: Hi, I'm asking because I've doing some simulations and I haven't been able to get the results I want, which is +/-5V.

Hi Team,
May i check with you for this part, do we have anything similar but higher ambient temperature? customer is looking for around 105 degC instead of 85 degC. Otherwise is there any alternative for this…
Part Number: LM27762 Tool/software: HI there,
What is the max output capacitance that the LM27762 can have on its outputs? Customer is looking at use 250uF (that he needs for bulk capacitance - not sure why that much).
Datasheet states control loop…
