FAN21SV06_12 Datasheet, PDF (4/17 Pages) Fairchild Semiconductor – TinyBuck™ 6 A, 24V Single-Input Integrated Synchronous Buck Regulator with Synchronization Capability

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.
