Absolute Maximum Ratings
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended.
In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability.
The absolute maximum ratings are stress ratings only.
Recommended Operating Conditions
The Recommended Operating Conditions table defines the conditions for actual device operation. Recommended
operating conditions are specified to ensure optimal performance to the datasheet specifications. Fairchild does not
recommend exceeding them or designing to Absolute Maximum Ratings.

While the recommended maximum inductor mismatch is ±10% for optimal current sharing and ripple-current
cancellation, there is no absolute maximum limit. If the mismatch is greater than ±10%, current sharing is
proportionately worse, requiring over-design of the power supply. However, the accurate 180° out-of-phase
synchronization is still maintained, providing current cancellation, although its effectiveness is reduced.
