Hello all

I'm trying to simulate LM10011 with TPS74201 to achieve a voltage regulator that is controlled by current.

Unfortunately, it seems that the IDAC_OUT current is not controlled by VIDA VIDB VIDC VIDS but only from the Rset.

I supply 3.3V DC to them and even pulses and nothing changes the output current.

Any suggestions please?

Hi Maxim,

Joe will take a look at this and help.

Maxim,

Have you tried to run this simulation with just the LM10011 device by itself (with a resistive load)? Also it might be easier to start simulating with the device in 4-bit mode first.

Looking at the unencrypted PSPICE model, it looks like the output should respond to the digital inputs for setting the current.
