    LM5019 provides a basic power-on sequence and provides a well-controlled and consistent start-up. In addition to 54 V, the TPS23881 requires 3.3 V for the digital circuitry and this is routed up to TPS23881EVM-008 over the connector interface. The current consumption is 6-mA typical and 12-mA maximum.
