LM61495-Q1: Margining

ranjith r

Part Number: LM61495-Q1

Tool/software:

Hi,
I am using LM61495-Q1 for our application.
Vin = 24V, Vout = 5V, Iout = 8A.

I need to margin the output voltage via external DAC. May be +10% to -10%.
Could you please tell me, how can I connect the DAC output in order to change the Vout of the LM61495-Q1?

I am attaching the circuit which I used
And also, please suggest a voltage DAC for margining it

Thanks

Hi Ranjith.

Please see https://www.ti.com/lit/an/slyt777/slyt777.pdf - this explains how you can adjust the output voltage.

Typically customers use the DAC available on the MCU on your board. If not - you can use the one mentioned in the above app note: https://www.ti.com/product/DAC53608

It takes in an i2c input. However, there are multiple other DACs available with TI (https://www.ti.com/data-converters/dac-circuit/precision/products.html#sort=1130;asc&) - let us know the application and the kind of control you have on your board (to change the output voltage) - a block diagram will help - we can recommend devices accordingly.

Thanks,

Best Regards,

Taru
