Notes:
1. Nominal values apply with sense pins
connected to +Vout and Ground Return
with other control pins unconnected.
2. Output derating applies at elevated
ambient temperature.
3. Typical efficiency taken at 20A load, 2.5V
output (3.3Vin device); 20A load, 3.3V
output (5Vin device); 18A load, 5V output
(12Vin device).
4. Mechanical Dimensions are nominal values.
5. Consult the technical reference notes when
available.
