AWR1843: LP87524TRNFTQ1 PMIC voltage

Part Number: AWR1843
Other Parts Discussed in Thread: , AWR2944EVM

Hello

 in our PCB we are using LP87524TRNFTQ1 PMIC IC. However, the latter works with an input voltage of approximately 5V but our circuit must be powered with an input voltage of 12V. Could you recommend a 12V to 5V buck converter to be placed before the PMIC (LP87524).
We also use the PMIC to supply voltages to the AWR1843 radar.
Any help ? thanks

    Hello,

    The LP87524 will accept 2.8V-5.5V. I would recommend to check the design files for AWR1843BOOST and AWR2944EVM. These boards both use a 12V to 3.3V pre-regulator that could be used in your case.

    Regards,
