Other Parts Discussed in Thread: LM5166,
Hello,
I am thinking of using your DC-DC LM5166 IC, and to make a first evaluation of it I decided to carry out some tests with your test tool LM5166EVM-C33A.
My final application will be a wireless transmitter and for this reason a low current sleep is very important.
My question is as follows. no-load consumption is too unstable and not specified in the documentation.
The changes introduced in the LM5166EVM-C33A were:
R 5 = O R
R7 = 24.9K
R9 = 1M
R10 = 560K
The accompanying chart is the result of the current measured by the FLUKE 2638A multimeter. Can someone tell me what could be wrong?
Thanks in advance for any help.
best regards
Rui Silva
