Hello!

Please help me to understand what resistors I should use to get +2.5 and -2.5 output from ADP5070 in SEPIC mode? I can`t use ADIsimPower unfortunately.

Is it right that I should use three inductors (or one coupled-inductor + one stand-alone)…

Is it possible to synchronize two ADP5070 without using externally generated signal? Just something like connect pins SYNC tohether with resistor to ground or Vcc to select 1,2 or 2,4 MHz?

I didnt find this information in datasheet. It is must for reduction…

Hi !

I'm trying to create a +5V and -5V for a 12V source with an ADP5070 using ADISimPower,
but the tool don't work on my PC.
I get a visual Basic error, a little help would be appreciated.

The data sheet mentions formulas for calculating inductor values in boost and inverting mode. I tried to apply this formula with samples from Table 10 (Recommended Boost regulator components) in the data sheet. But i was not able to get a match. Have…

Please provide suggestions for my design layout. I have separated power components & feedback components.

Also eagle gives me dimension errors for all pins of the ADP5070 !

sir,

i want to make dual supply output with single supply input. So how to get 39 V dual supply of ADP5070 EVM with 12 V input.

What kind of capacitors should be used at COMP1 and COMP2 in the ADP5070. The tool gives me a 1.5uF capacitor. It has not mentioned what kind?

I am in doubt since i thought of going for MLCC caps, but for this value it was not available.

ADI专家，你好，我现在有个应用，里面用了AD7194和运放AD8656，我用ADP5070+ADP7102,ADP7182做正负电源供电，其中+5v还作为AD7194的模拟电源，我想问的问题是AD5070中PGND和AGND应该怎么应用，我需要将ADP5070的AGND和AD7194的AGND相连接再和PGND单点连接吗？我现在的做法是将ADP5070的PGND、AGND与数字地都连接在一起，然后和AD7194的AGND单点连接，这样做会引入噪声吗？怎么做才合理呢？谢谢各位专家抽出宝贵时间帮我解决问题…

Hi,
I use a ADP5070  for gernerating +/- 14V by a 5V USB power supply.

I designed my board with the tools and pretty simmelar to the LTspice model which is avaleable.

I pull EN1 and EN2 up to 1.4V and i did not connect the SEQ.

Then i get my -14V at the…
