TPS709: EN Pin current

Part Number: TPS709

The customer want to know when increasing EN pin voltage, whether the EN Pin current will decrease?

TPS709 is used in a special case. The EN pin driving current is very limited.

    Hi Fabio,

    EN is pulled high by a 300nA current source, and therefore EN can be left floating to enable the device. The 300nA is sourced from IN, rather than being sunk through the EN pin. EN pin current does not vary significantly with VEN.

    Regards,

    Kelsey
