Note 1: R_DSON is characterized at 600mA and tested at lower current in production.
Note 2: Regulator VSW pin is forced off for 240ns every 8 cycles to ensure the BST cap is replenished.
Note 3: For the adjustable version, the ratio of VCC/Vout cannot exceed 16.
Note 4: Based on Over Current Detect testing
