Part Number: LM2611
I want to know how to generate -2.5V with this part. I read the datasheet and I don't see any reference in how to configure the part. 8.2.3.1 Design Requirements This design converts 9 V (VIN) to –5 V (VOUT). Adjust RFB2 to set…
Part Number: LM2611 I'm noticing some very odd behavior with my design for the LM2611. I'll give you some quick specs: L1: 22 uH
L2: 47 uH
Cin: 22 uF
Cout: 23.1 uF (three caps, one 22 uF, one 1 uF, and one 0.1 uF)
Ccuk: 2.2 uF
Vin: 13 V - 13.9…
Part Number: LM2611 Other Parts Discussed in Thread: LM2664 Hi sir,
For AN–1203 LM2611 Demo Board,
In condition of Vin5V、VOUT-5V、Iout≦300mA, this EVM use inductors of CR32-220(Sumida).

Part Number: LM2611 Hi Team,
Can you please help to -
1. review the schematic
2. confirm whether the inductor selected is fine.
3. let me know if the inductor is overkill.
VIN = 12V
VOUT= -20.5V (negative)
IOUT = 0.2mA
INDUCTOR L27 & L28 = SRN6045…
Part Number: LM2611 Other Parts Discussed in Thread: TPS28225 Hi,
My customer is evaluating LM2611 on their board and switching stops as below.
Schematic is below.
Do you know why switching stops and VOUT rises then?
Best Regards,
Kuramochi
Part Number: LM2611 Hello, I would like to make power supply with input voltage +5v and output voltage -12v ( 260mA). Can you help me with the circuit?
Thanks!
Part Number: LM2611 Hi Team,
My customer, when testing SW voltage, found its negative spike lower than -0.4V, as which is the absolute rating noted in datasheet. Could you please kindly check if we have an AC rating for it? Thanks!

Part Number: LM2611 Hi,
My customer is evaluating the LM2611 and wishes to reduce the inrush current at startup. He is using the TI Dev board, +5V input and -5V output and a 390ohm load resistor.
With 300mA limit enabled on the PSU it does not start correctly…
Part Number: LM2611 Hi,
We refer to the soft-star schematic of LM2611 datasheet in our design, and the voltage is step up from 12V to 12.8V(input 12V and output 12.8V),
the PCB is short circuit when the power on, can you help to check the schematic and…
Part Number: LM2611 ...solder an 8.2K ohm resistor across Rfb2 (10K) and then a 560K ohm across Rfb1 (29.4k) ohm resistor. Rfb2 actually has a few thru-holes in parallel with it, so it's novice-easy, but Rfb2 has none so it'll be a little trickier.…
