No-load quiescent current draw on ADP5301 is too high

My evaluation board is configured for PWM (Sync/Mode pin is at Vin). The output is set to 3.0 volts and the input is 5.0 volts. With no load, the current draw is 5.75 mA. If I configure the regulator for hysteretic mode, the current draw is per the datasheet, 170 nA with occasional switching. The datasheet specifies the PWM quiescent current at 425 uA. Could I get clarification on PWM no-load current draw?

 

Thanks,
