DCDC_LP Not Turning On

Hi there,

 

I have designed a custom board around the MIMXRT1052DVJ6B by referrencing the IMXRT1050-EVKB board. 

I have all my supplies up and running. Then PMIC_ON_REQ turns on the DCDC_IN supply and a RC filter goes to DCDC_PSWITCH with plenty of delay, but I never seen any voltage on teh DCDC_LP pins. 

 

Are there any other requirements that I may be missing to get it to turn on? 

 

Thank you
