Part Number: LM2611 Tool/software: I tried to generate -20V DC output voltage with +5V input with LM2611 EVM and LM 2611 with similar circuit design.
When i use a power supply with current limit setting more than 1.5A. It can generate -20V well with…
Part Number: LM2611 Hi Experts,
LM2611 is mass production on customer side. There is a issue when they testing it:
1. When the supply voltage under 2.5V(less than the minimum working voltage), the the SW is short to ground, is it the normal status for…
Part Number: LM2611 Hello,
despite searching effort I have not found any clear answer, what this parameter on the p. 10 of the LM2611 datasheet stands for.
Could you please help me with this one? According to general convention, it shall be some kind…
Hi Harry and Niklas,
Thanks for your suggestions. As of now, I would like to work on LM2611 testing. I will update you on the test results on the another thread.
Part Number: LM2611 Hi,
We want to provide some delay in the output voltage start up for +5V to -5V conversion using LM2611 converter. For providing the delay, we are using a RC network. We have connected 1M and 33nF RC network to the Shutdown pin (SHDN…
Part Number: LM2611 Other Parts Discussed in Thread: TIDA-01457
I need a -3.81 .1A typical, .15A max regulator. It will power RF circuitry, so it needs to be quiet as possible.
I’m more of a digital designer, and definitely out of my comfort zone with…
Part Number: LM2611 Hello Team,
I can see the Grade A and B have difference in Current limit value.
Is there any reason LM2611 has 2 kinds of current limit? Thank you!
Hi Niklas,
While debugging, I have found the below observation:
Case 1: With the SHDN pin connected to the VCC directly, If I supply 12V at the input to the regulator, the output voltage of the regulator is -4.88V. When I connect a load at the -5V rail…
