The JEDEC low-K (1s) board used to derive this data was a 3in × 3in, two-layer board with 2-ounce copper traces on top of the board.

(2)

The JEDEC high-K (2s2p) board used to derive this data was a 3in × 3in, multilayer board with 1-ounce internal power and ground.

(1)

The design principle allows only VINDCDC to be the highest supply in the system if different voltage input supplies separately to DCDC

converter and LDOs, meaning VINDCDC

≥ VINLDO1, VINDCDC ≥ VINLDO2.

(2)

The max quiescent current of enabling LDOs is 8mA higher for TPS650001, TPS650003, TPS650006 and TPS650061.
