ZHCSJ10B September 2006 – November 2018 TPS2376-H
PRODUCTION DATA.
The TPS2376-H includes a power-good (PG) output for use as a dc/dc converter enable once the load capacitor is fully charged. The PG pin is the safest way to ensure that there are no undesired interactions between the inrush limit, the converter startup characteristic, and the size of the bulk capacitor.
The PG output is pulled to RTN whenever the MOSFET is disabled, is in inrush current limiting, or the V(RTN) rises above 10 V. The PG pin goes to an open-drain state approximately 150 μs after the inrush current falls 10% below the regulated value. PG pull down current is only specified for V(VDD-RTN) greater than 4 V, below which the dc/dc converter should not be able to operate. The PG interface to the downstream dc/dc converter is simplified by referencing it to RTN.
The PG pin can be left open if it is not used.
