Hello,

In the selection table for inverting regulator it's specified that ADP5073 can deliver 1.375A.

Here is simulation setup where I check its capability to generate -30V from +5V.

The values of Rfb, Rft, L1, etc. I took from datasheet hint table…

Hi

I can't find the maximum operating voltage on the ADP5073's EN pin in the datasheet. I see that the absolute maximum voltage is +6 V but what is the operating maximum voltage?

Regards, Jonas

Hi

The ADP5073 datasheet states that the SLEW pin can be set to fast, normal or slow. The noise will be lowered by slowing down the slew rate, but the efficiency will decrease.

My question is: How much lower will the efficiency be when setting SLEW to…

Hi

I have a +5V to -15.5V inverter based on the ADP5073. Design based on the Design Tool. I used an output current of 100mA and the tool indicated ADP5073. Though the effective current on steady state is only around 20mA, the startup current is high due…

Hi, 

I have some problem with ADP5073.

I tried to get a Vout = -10v, with VIN = 3.3V using the circuit in datasheet.

I gave VDD  (I tried 3.3~5V) and found that VREG was about 0.3V.

It means that I can not turn on the regulator.

I tried to send a 3.3v to…

Hi,

We have experienced a series of problems with ADP5073. I hope this could help someone with similar issues.

The design is same as the application circuit in the datasheet and the design tool, with 12V input and -2V output. Parts are selected from…
