For non-sync options, we have 75V Vin max parts: LM5575 (1.5A) and LM5576 (3A)
If you don't need high current, we also have LM5161 (100V 1A), LM5017 (100V 0.6A), LM5006 (100V 0.6A).
Note that the current rating of the buck needs to be higher than…
Other Parts Discussed in Thread: LM5006 , BQ24085 Hi,
I am using the LM5006 and looking at single-cell Li-Ion chargers. I have seen other battery management systems that are able to send feedback from the charger to the regulator so that the regulator…

Can you provide an Excel worksheet that simplifies the design of the LM25066? Thanks.

Hi,
You can change the frequency of LM5006 easily by modulating its RON pin (within reason). For example, this app note varies the frequency for low dropout but a a uC DAC can also achieve the same result. You will have to verify all the boundary conditions…
Hello Guilherme,
When using WEBENCH design, you got to use the exact BOM or close. If you deviate from the WEBENCH generated the BOM, there is no guarantee the device will function normally.
It's difficult to tell why the device burned up without seeing…
My maximum load is 500mA, so I can't use LM5008A (350mA).
Max VIN is somewhat unbounded - a faster generator will give me a higher voltage. I can protect against overvoltage but a higher Vin(max) makes that less critical.
I am currently using the…
Other Parts Discussed in Thread: LM5007 , LM5085 , LM34923 , LM5006 , LM5017 Dear comunity,
Can anyone give me an idea what is difference between adaptive on-time D-CAP2 mode and Adaptive Constant-On-Time (COT) control mode? I am not sure it is same operation…
Hi Stefan,
In Buck-Boost mode the abs max between the VIN and GND pin is (VIN+VOUT)=24+15=39V which is really close to the abs max 42V of the IC. It is possible to that there are spikes above 42V. The buck-boost circuit current flow is different than…
