LM2576HVS-ADJ/NOPB

Other Parts Discussed in Thread: LMR23630, LM43603, LMR33630

Dear Sir,

I am using LM2576HVS-ADJ/NOPB to Power my micro controller and other peripherals.


Input Voltage:24 VDC
Output Voltage: 5V, 3A


I think this IC will have some noise at output while measuring analog Input signal.we observed count variation at micro controller analog input pins.

I want a equivalent IC with very low noise output.

Please suggest the part number.It would be great full, if you provide Switching Regulator and LDO for same application.I know Input range is High and output current is High.may be LDO not a efficient solution.

Regards,
Murthy

    You might want to look at the LMR33630 in the soic package or the LMR23630 or the LM43603

    Keep in mind that "noise" is very dependent on the PCB layout.  I would order an EVM and test

    carefully in your application.  Then use the EVM PCB layout as a guide.
