AWR1642BOOST: TIDEP-0092

Part Number: AWR1642BOOST

Hi 

Per the Short Range Radar Reference Design TIDEP-0092,  the PMIC used (LP87524BRNFRQ1) has 3 enable pins PMIC_EN1/2/3 presumably to enable the buck regulators.

But since there are 4 buck regulators for each of the 4 rails (3.3V, 1.2V, 1.8V and 2.3V) with only 3 enable pins PMIC_EN1/2/3. How is the 4th rail enabled?

Thanks,

John
