REVISION HISTORY
Changes from Revision May 2012 (#IMPLIED) to Revision A Page
• Deleted V
FBTH
- T
A
= 0°C to 85°C, V
O
= 1.05 V, continuous mode from the Electrical Characteristics. ............................... 3
• Changed V
FBTH
- T
A
= –40°C to 85°C, V
O
= 1.05 V, continuous mode From: MIN = 751 MAX = 779 mV To: MIN =
754 MAX = 776 mV in the Electrical Characteristics ............................................................................................................ 3
• Changed the Over/Under Voltage Protection section. From: "as the high-side MOSFET driver turns off and the low-
side MOSFET turns on" To: "as both the high-side and low-side MOSFET drivers turn off" ............................................... 8
