Hello,

We do not have exact replacement for LT device you mentioned. The closest TI device with split rail output (+/- output) with the voltages you specified is TPS65131. Its datasheet is available online.

Kind Regards,

Liaqat

Hi Liaqat

If LTC is not used, the conditions are as follows: Input voltage 12V Switch to 2 voltages.

The first voltage is 12V input to 5V~27V output, (FB will be used to adjust the Output voltage) Output current max 3A.

second voltage 12V input to negative voltage -1V ~ -20V, (will use FB to adjust Output voltage) Output current Peak 3A.

Ps. It is better to be the solution above Dual Output.

Hello,

I am busy with some other customer support issues but will look into your query and get back to you by Monday my time (California).

Hi Gareth,

Unfortunately, I do not see a solution in our portfolio to meet these specs. Almost all of the devices in our product line are 3-6V input devices but let me assign this thread to a product line that has wider Vin devices and someone may respond with a possible solution.

Kind Regards,

Hi Gareth,

For the first voltage, you could take a look at LM5176,

I don't have recommendation for the second voltage.
